A friend of mine recommended me this fic WAY back when it was being written. I recently gave it a reread and I'm going to say this about it:
The first two parts of this story almost made me give up on reading part three. Moreso on part 2, which I'll eventually cover. That's... not a good thing. Like at all. But I did continue and unlike the other trilogy that I covered on here, part three is vastly superior to the first two. I'm also not going to count the fourth story in this, because it doesn't need to be read and can stand out on it's own.
And here we go. The Mercy of the Fallen series!
Series: Yami no Matsuei
Genre: Angst, general, casefic
Warnings: Boarderline OOC Hisoka, mentions of sex, mentions of rape
Couple (if applicable): Tsuzuki/Hisoka one sided (!!!), it's more Tsuzuki + Hisoka
Plot: 7/10 - Okay, I'll say this on the plot. The casefic itself? Fits the YnM universe perfectly. Wonderfully researched as well, and a better example of how to use fucking cliffnotes. We don't need the background info, but it's there incase the reader wants to see how it ties into the story. This won't be the only example in this series.
However, the problem isn't the plot itself, it's really Hisoka's character, and it somewhat drags the plot down with it. Like I can understand him wanting to be alone with his own thoughts and emotions, more so because he's an Empath. But leaving RIGHT after the Touda incident? Yeah, no. Hisoka would damn well know better than that, even if you claim ignorance on his behalf. And then debating to send Tsuzuki back? At least he caught on that would not be a good thing.
Also, if Hisoka could feel anything coming from Tsuzuki, it's a wonder he survived with him up to this point. Maybe I haven't read the manga/watched the anime in a while, but couldn't Hisoka only pick up strong emotions only if he was touching Tsuzuki, at least pre-Kyoto arc? I remember him picking up some of Tsuzuki's emotions, but near the beginning of the manga/anime. I'm assuming he got better as using his powers over time, and I'm pretty sure Konoe was training him in the use of his powers.
Again, don't know if it's a fanon thing about Hisoka's powers or derivived from canon. I decided not to dock any points for that, because I really can't remember if it's a canon or fanon thing.
Not to mention, Hisoka is down right cold to Tsuzuki. I'm going to cover this in the characterization part more deeply.
Overall plot is okay, but the lead in to get there? Not so okay.
Writing: 7/10 - There's nothing wrong with the writing besides maybe an awkward sentence here and there. It doesn't derive from the story and that's what's good about this series. The writing only seems to improve more as the series continues and that's how it should.
Characterization: 3/10 - This is where the story suffers in my opinion and it's all on Hisoka here. I don't like the characterization of Hisoka in this series at all. I dislike it a lot in this part, and moreso in the next part, but we'll get to that later.
Like I said before, Hisoka is down right cold to Tsuzuki. I mean, like I said, I can see him wanting to be alone to get his thoughts and emotions in order. But even I know that just up and going and not telling Tsuzuki where he's going directly AFTER the Kyoto Arc??? No, not going to happen, sorry. This story would've benefitted more if it took place a week or two AFTER the Kyoto Arc, but it doesn't. And Hisoka would probably either tell Tsuzuki about needing alone time to think, and maybe put an empathsis on his powers as the reason why (And it would actually be truthful too), or be really sneaky and take time off when they're allowed to work again, because he knows Tsuzuki has little to no vacation time due to him blowing up the library again and having to pay it back.
Also, Tsuzuki comes on WAY too strongly, but in a way, I can see why. Hisoka basically tells him to live for him and then RIGHT after, up and walks away. So Tsuzuki's character is believable. I could also see Tsuzuki guilt tripping and hiding as well. So Tsuzuki's character isn't really the problem.
This is just... really uncomfortable to read sometimes, and it's mostly because I feel like Hisoka is on the cusp of being OOC to remaining somewhat IC. Basically, when the focus of the story is the case fic itself, Hisoka's perfectly IC. The only time is when they want to sync up to each other (aka, Hisoka is being stupid and illogical, when he's usually the logical one), but the reason behind it, I can let it pass, for plot's sake. When it comes to focus on Tsuzuki, it's cold and clinical.
Negatives: Boarderline OOC Hisoka, rape mentions
Summary: Post Kyoto Arc, Hisoka wants time to think and reflect. Surely a deserted mountain is the perfect place for that? Too bad life (or afterlife) doesn't work that way...
Overall: 5.6/10 - Not a good start to the series. If you're looking for casefic and don't care about pairings at all, this actually is probably one of the better ones. I'd recommend it only because the casefic itself is very well written.
Next up, is probably the weakest part of this series. And if you thought Hisoka's character was bad here? Nope. Part 2 is what almost made me give up on reading part 3.
