I didn’t expect the killer to have gotten Lynn. She would have been murdered had Arne not turned her.

I’m really curious to know who the killer is and why Arne chose Elise as his prime suspect. If she really is involved, maybe it’s a Jekyll and Hyde situation with her? She transforms into a beast and that’s who’s been killing/attacking folks?

mmcjawa_reborn2026-01-27 19:04

I don't think Elise is...I think he just wants Lynn to prove she isn't for entertainment value

diacewrb2026-01-27 19:58

Or like the theory that the fastest way to get the right answer is to have someone else give the wrong answer first.

ObvsThrowaway51202026-01-28 01:44

Ah, perhaps that’s it.

TyraniTEMPESTar2026-01-27 19:19

Hmm so there's supposedly multiple persona's / consciousness / soul or whatever all residing within Lord Arne?
The nine vampire kings, but only one heart.

Just looked at the [MAL](https://myanimelist.net/character/282434/Nachzehrer) list of characters and skimmed through episode 2. This Nachzehrer character has the same yellow eyes as the hooded "monster" that we got a brief look at, and its hand was like a claw, and its face somewhat resembled like maybe a werewolf-ish...?

Kinda weird that the guard dogs decided to attack Lynn all of a sudden. I was thinking maybe the [Nachzehrer](https://en.wikipedia.org/wiki/Nachzehrer) could've been one of the guard dogs occupying Mr. Reinweiß on his walk throughout the town in episode 2.
But according to the wiki description of *Nachzehrer* they're an animated corpse.
So I'm guessing Mr. Reinweiß was "successful" in bringing his "wife" back to life....
But now she wants to take her family back to the grave with her.

Tradition_Leather2026-01-27 19:47

I think the lore is that Arne should have 9 hearts, from the projector story around e2

It's a bit weird that the showering started bc of a comedy scene and turned out very seriously.

In the beginning when they met that Arne had no reflection in the mirror, but after Lynn got turned, there's her reflection in the mirror...?

RealMr_Slender2026-01-27 20:45

It might not transform her overnight, the mirror boy hinted that it was a process

guineaprince2026-01-28 05:03

It could be there's some benefit to her own blood already circulating in Arne, so perhaps she has a little bit more of her humanity. Becoming a vampire through the combined blood of a vampire lord and her own original mortality... that sounds like a suitable excuse for Main Character exclusive.

Course I also like to imagine that her seeing her mom was last moment we ever see Lynn. She dies, the vampire takes over. Tho I guess having the blood of her original host returned might also give benefit in that scenario.

DugACCat2026-01-27 20:16

I guess I should have predicted that, this being a vampire connected story, but for some reason it took me entirely by surprise. I was still pondering how the blood smell probably came from the tracksuit (which I still can’t get used to) and then suddenly she’s bleeding to death in the tub.

Tradition_Leather2026-01-28 13:14

Yeah, the blood smell -> showering is definitely a comedy scene, and it turned out to directly connect with the serious murder plot.

NanDemoKnaives2026-01-27 20:35

I thought this arc would finally wrap up here but there's another episode, I feel at this point it's being dragged out.

But damn Diana, telling to Lynn's face she's glad her father's dead, these servants don't hold back.

Fools_Requiem2026-01-27 22:09

> But damn Diana, telling to Lynn's face she's glad her father's dead, these servants don't hold back.

Just making it easier for her to leave. No one where is worth sticking around for anymore. None of them cared that her father was dead. ~~Fuck em. I hope they enjoy unemployment.~~

Edit: Forgot about the "entertaining the guests" thing.

Exciting-Pie61062026-01-28 03:44

Well, let's not forget her father was pimping out his maids to guests.

From the POVs of the maids, I can understand their feelings.

Fools_Requiem2026-01-28 15:12

Yeah, I forgot about that. This show kinda breezed through it making it easy to forget, though.

rotten_riot2026-01-28 09:09

>None of them cared that her father was dead. Fuck em. I hope they enjoy unemployment.

Her father was a pos tf??

Fools_Requiem2026-01-28 15:11

I forgot about the "entertaining the guests" aspect. In my defense, they sped through that in the show as if it wasn't relevant making it easy to forget. This show isn't exactly well constructed.

Do think that sets this up to be a Murder on the Orient Express situation where all of them are responsible.

rotten_riot2026-01-28 09:26

I watched episode 2 to 4 back to back and it still feels unnecessarily long. Can't even imagine how tired people who watched this arc weekly are feeling rn.

Tradition_Leather2026-01-28 13:08

Diana gives me yandere vibes from her interpretation of love

BaytaCosmico2026-01-27 20:38

Wait wait, so the Lynn we see in the first episode is already a vampire?! A vampire otaku who becomes one herself. I wonder if that was always her plan after giving Arne her blood as an advance.

Arne having existential crisis was unexpected. So that's why he was acting a bit strange and cold last episode. Because this evil king was in control. And all it took was one slap from Lynn to exorcise him and get Arne back in control.

I'm really not following the whole father killing mystery. They introduced a whole lot of characters and motivations in a rush and didn't do a good enough job of it. So I'll be glad when we're through with this mystery and move on to the next.

mekerpan2026-01-27 21:07

I am thinking the first episode actually occurred first (after all). Remember -- in the concluding there is mention of Lynn being the mystery solving young woman. But I could be wrong -- things seem awfully confusing so far.

ParasaurolophusZ2026-01-28 05:27

That's from the rumor that Zisye spread, I think.

BaytaCosmico2026-01-28 07:28

It can't have occurred first because Lynn only met Arne during the beginning of this current arc and it was clear they'd been together a while in that first episode. They had the necromancer girl with them too whom they're yet to meet in the current timeline.

Fools_Requiem2026-01-27 22:06

> I'm really not following the whole father killing mystery. They introduced a whole lot of characters and motivations in a rush and didn't do a good enough job of it. So I'll be glad when we're through with this mystery and move on to the next.

The whole thing is a mess. I need more Undead Murder Farce type stuff, and less of this poorly done Clue shit.

BaytaCosmico2026-01-28 07:26

Agreed. Either the source itself has shoddy writing or the adaptation is bad. I'm really only watching this still for Lynn and because Uchiyama Kouki is in it.

rotten_riot2026-01-28 09:27

>I'm really not following the whole father killing mystery. They introduced a whole lot of characters and motivations in a rush and didn't do a good enough job of it. So I'll be glad when we're through with this mystery and move on to the next.

Atp I'm ready for the resolution to be disappointing cause they really chewed more than they can swallow

tripleaamin2026-01-27 21:31

Pacing for this case is not good. I do think the multiple personalities inside of Arne are interesting and, honestly, are much more interesting than this case. With that being said, I wasn't expecting Lynn to be turned into a vampire in this episode.

flightlessCat92026-01-27 23:51

I'm not following on all this vampire jargon BS, who has whose blood in them and who is drinking whose blood and what its going to do.

I feel like the clues are fairly light but they're spending 3 weeks on this, and I forgot the important points from 2 weeks ago already. Like I'm not going back to see which scene has a mirror in it. At this point I'm just watching them solve the thing instead of trying to solve it along.

Shifty_132026-01-27 23:58

Yep, this watches like trash. Though it's still mildly entertaining.

So far first ep was the best. After that it's all just one big rushed mess that doesn't make much sense.

I noticed how story/presentation really resembles detective games. I have warm feelings connected to those so I will keep watching this just for cozy gaming vibes.

And it's interesting how this is actually a game:

[https://store.steampowered.com/app/1322290/The\_Case\_Book\_of\_Arne/](https://store.steampowered.com/app/1322290/The_Case_Book_of_Arne/)

But yeah, the anime is still pretty mid.

axlorg82026-01-28 04:33

Honestly id recommend playing because it genuinely isn’t a long game and pretty cheap as an indie

Striking_Chard24202026-01-28 05:08

Dang no idea this was a game adaptation. Pretty interesting

YlfaTheForsaken2026-01-28 00:21

That's crazy, imagine telling a kid you're happy their dear ol' papa got violently murdered in his own home. Like I get there's a certain freedom in death, but dang. No remorse whatsoever. Was he a bad employer before there wife's death and got worse, or was he okay then got bad?

She got turned into a vampire pretty quickly. I mean I guess that makes sense in a vampire show. Okay so then like does each heart have it's own personality? When does the necromancer come into play? And that orange doggy demon looking guy from the opening show up?

rotten_riot2026-01-28 09:20

>Was he a bad employer before there wife's death and got worse, or was he okay then got bad?

Gordon (butler) told Lynn her father used to pimp the two maids to guests. Of course they're happy the old shit is dead lol

djthomp2026-01-28 02:33

Poor Elise, nothing goes well for her and now she's been tapped by Arne as the false suspect that Lynn is supposed to refute. Or at least I assume that's the play.

Big mistake in an ongoing murder mystery to go somewhere defenseless and alone like the giant empty bathroom.

I wonder if Lynn being a vampire gets reversed somehow. Normally that's just not usually a thing, but it sounds like she had a reflection at some point in episode one?

JoeyDee92026-01-28 02:35

In the final scene we can see Lynn in the mirror talking to Zisye. In an earlier episode we learned that Arne could only talk to him from the little pocket mirror or in the castle. Something tells me there's a whole lot of lies going on. Rewound that last scene like 5 times trying to tell if she was reflected in the mirror or if it was just supposed to be some transparent thing, but it's got to be her reflection.

The boy who cried wolf telling Lynn she's a vampire now? Arne did something, but that something wasn't turning Lynn. I also think something more supernatural is going on, another vampire trying to resurrect one of Arne's hearts using Lynns dad as a catalyst? Those imposing feet of Lynn's killer could be just about anything...

rotten_riot2026-01-28 09:22

Atp I wouldn't be surprised if it's the show forgetting their own rules tbh

Golden_fsh2026-01-28 03:19

Yeah, think I might drop this show which is a shame because the first episode was great. This whole murder mystery is being dragged out and I don't understand Lynne's barely reaction to finding out that the house staff are a bunch of psychpaths.

I wish the kid in episode 1 stayed alive because he was more interesting as a detective 😭

Striking_Chard24202026-01-28 05:13

Was hoping Lynn to be a practicing witch or something 'cause that would definitely be a fun cast of characters but I guess good for Lynn for becoming what she loves 😅 This show seemed to have a lot of potential at the start but it's starting to drag especially with this whole (confusing) whodunnit plot and weird pacing. Like what do you mean Lynn was just taking a bath after a 'lighthearted' moment and the next scene is her literally dying.

NoHead17152026-01-28 06:57

That was a surprise vampirification. So it turns out everyone in the first episode was non-human from the get-go. Not sure if Lynn will show some powers soon or just remain essentially human.

SYZekrom2026-01-28 11:14

Zamn, so she's a vampire. Like I kind of said in a previous episode, I love the mixing and contrast of a fun, comic worldview with a serious, tragic worldview. How a gag event like rushing off and taking a shower b/c she gets embarrassed by the fact that she smells gets forced into a serious storyline where it means she left herself defenseless and alone in the bath. It's such an unsettling feeling when the balance of separation and mixing is just right.

Sacramentlog2026-01-28 14:30

So is it this vampire's hobby to walk around and watch children die after he helps them to try and solve the case of their parents murder mystery?

This is twice now in 4 episodes. Does he not care about the kids he's following around, is he too lazy to warn them or intervene before they get killed or does he get off on it?
