The Kagerou Project is a multimedia series by song producer Shizen no Teki-P. The series focuses around the story of the Mekakucity Dan, a group of teenages with supernatural eye abilities. While originally it existed as a number of Vocaloid songs sung by Hatsune Miku and then I/A, it would later be adapted into a manga series, anime, and light novel.
Power of the Verse
The Mekakucity Dan itself isn't impressive physically, with its strongest character capping at Building level, however some of its eye users have a number of mind-affecting or status-inducing abilities that can be used on an opponent regardless of durability. Outside of this, however, most of them are normal humans in every other aspect.
Surprisingly, some notable characters like Marry and Azami have shown Universal+ feats through the use of the Combining Eyes; the most powerful eye ability in the series with the power to unite the snakes and manipulate and even create a universe (Heat Haze) and preform universal time resets. While individually the eyes aren't that notable, Azami and Marry can possess all of the eye abilities shown in the series (In Azami's case, far superior abilities), which gives them a powerful range of hax.
