The first episode left, and this show already reminds me of Kyoukai no Kanata.
Both have a strange girl and melancholic boy with superpowers who are fighting against evil youkai. These shows also have a similar supernatural atmosphere with some romantic relationships, so if you are a fan of KnK, give In/Spectre a try.
The same circumstantial event when girl with special ability finds boy with a different special ability and from there on boy's life was never the same again when he finds himself being drafted into service by the girl into fighting supernatural entities.
In/Spectre and Beyond the Boundary are two supernatural anime about a short-haired girl and a boy who both have supernatural abilities—the girl is personally associated with supernatural beings and the boy is seemingly immortal. The two eventually form a relationship due to their supernatural connections.
An immortal boy who has connections with otherworldly creatures.
A girl with a mysterious and disturbing past.
Fighting, and uncovering the truth behind these "yokai".
Both shows feel eerily similar (so far), but that's not a bad thing.
In/Spectre and Uta Kata are two fantasy anime directed by Keiji Gotoh, and despite the latter anime's cover, both shows actually have somewhat similar levels of slow pacing and dark storytelling. The main character in both shows is a girl who has feelings for a boy who is several years older than her. She also has connections to (as well as can see) spirits, which was eventually given to her with a heavy price.
The protagonist is a teenager that can see youkaï, spirits and other paranormal beings
Some youkaï see the MC as someone who can help them, some others see the MC as a target or a threat
Natsume Yuujinchou is however more light-hearted (in a certain way, because it also deals with a lot of drama and sad stuff) and more a SoLesque anime than Kyokou Suiri
Welp, I can say, the shows is kinda same, but most of them not.
Unlike Jibaku Shounen Hanako-kun, the main character of Kyokou Suiri serial is a demigod. Both series is talking about somewhat of "demolishing" the exaggerated youkai(s).
Both animes are similar to the main characters, a couple who are investigating paranormal affairs. There are sympathies between Tilarna and det. Kei Motoba in Cop Craft and Kotoko Iwanaga and Kurou Sakuragawa in In/Spektre, but without showing impassioned feelings, they show this with their amusing dialogues and behavior.
Both anime are based on manga/novels written by the same author. Because both are from the same author there are a lot of similarities, such as
- both dealing about something supernatural
- similar characters (Aika & Hakaze are together Iwanaga; Kuro being very similar to Yoshino)
- both being detective stories, although Zetsuen has just one big mystery
and so on. If you enjoy one, you might consider giving the other one a try as well
Looking for a mystery anime set in a world with paranormal happenings? Both shows solve mysteries whyle showing the past and background of the characters - which is definitely not "normal" or "usual". Both shows have a male and female lead who are geting to know each other throughout the series. The vibes of the two anime is somewhat similar too in my opinion.
