Under all the Ho Yay, Scenery Porn, and Fanservice, Adekan has more than enough Nightmare Fuel to keep you up all night, between monsters, madmen, and a massive unsettling conspiracy run by a clan behind the scenes...
- In the first volume, the Copper Demon hunting an innocent young girl is utterly horrifying even if it is only a mask.
- The very first story shows Shiro being befriended by a kind but poor neighbour woman, Mitsu, who takes in abandoned babies and cares for him. Mitsu turns out to have been killing the babies so she could horde the money for their care and give it to her lover, who'd promised her they would be married once he had enough to escape the gang he was in. Not only that, but the guilt of her crimes drove her to madness, causing her to black out and wander around in a bloody wedding dress, and hallucinate the demonic shades of the babies she'd murdered. Brrrr...
- "Onna-neko... help me..."
- Kusuko's insane father is terrifying enough: a powder box merchant who enslaves low-born young women and sells them to men to be abused, after murdering his low-born wife for unverified suspicions that she was cheating on him, he then turns around and imprisons his daughter in a Gilded Cage while telling her terrifying tales of the outside world...and having sex with a girl who looks like a carbon copy of her on the side. Not horrifying enough for you? To keep his daughter in line, he tells her scary stories about a monstrous yuurei, Nainai-sama, who haunts their box-maze mansion. Except Nainai-sama is real...
- Everything that happens to Ippei after he gets captured and enslaved for use as a tool against Anri qualifies as this, including being the front-line witness to the triple murder-suicide of his new master, his new master's boyfriend, and his new master's pregnant wife, in an epic case of Murder the Hypotenuse. Keep in mind that Ippei is a sweet kid who idolizes Kojiro and has trouble standing up to people and saying no in the best of circumstances...
- How he falls into the part of town where half human cannibals live.
- The taxidermist. Dear god, the taxidermist...
- Anri and Shiro's backstories.
- Anri deliberately makes himself into Walking Fanservice. From what we've seen, his reasons for doing this were less than family-friendly. There's also his general psychotic nature which once led him to cut off two of his subordinates arms because they were arguing too loudly and it annoyed him.
- The half humans which are excluded from regular society, for good reason. They're cannibals and if one should happen to fall into their domain...
- There are numerous bitches in sheeps clothing in the manga that make extremely unsettling nightmare faces and have sociopathic natures.
- The worst had to be the Alpha Bitch who's tormenting of a poorer but prettier girl including having her raped and beaten and she later tried to cover it up when she believed she returned but has lost her memories of the incident including trying to kill her.
- The Nehates are made of Body Horror. They are huge ugly men with huge boils all over their body and they are unstable in nature.
- Anri threatens to rape a guy at one point and gets on top of him. It's horrifying even though Anri ends up stopping and admits he was kidding.
- Spider fights with poisonous bugs and nearly has his arm chopped off at one point.
- Shiro is impaled with spikes and two guys nearly chop his arm off as well with a knife.
- The introduction to the Southern Troupe's leader. He sees his men begging for forgiveness, dangling over a cliff for their execution. The leader just callously listens to their pleas and dismisses them, sending them over the edge. Keep in mind that the group of men he executed for failing him was enough to fill a large fish net.
- And when another one of his blood brothers protests about the excessive nature of the executions, he squishes that man's head with one arm. He then orders the execution of that man's entire family line straight afterwards. Not only do we witness the horror of the Lack of Empathy towards hundreds of lives, we see a socially untouchable tyrant willing to end clans if their opinions aren't shared.
- The true leader of the Ha clan, despite looking delicate, is just as viscous as the rest of the people under her thumb. She claims she wants Shiro and is betrothed to him, but as we see with the bodies of the rest of her previous "husbands", he won't like ending up with her one bit.
