Nana Abe

Probably the second oldest chuunibyou in fiction, only being beaten out by Ichiban from the Yakuza: Like a Dragon series. Claims to be "Eternally 17," yet ISN'T voiced by Inoue Kikuko, but is likely about a decade older, though her short height certainly isn't helping. She works as a maid with a bunny rabbit theme and plays up all the cuteness you could possibly imagine with such a profession. All while claiming to be some sort of alien magical girl from Planet Usamin, what is this, Sailor Moon? Well she also seems to not be too good at acting though, since the other chuunibyou, Ranko, pulls off her imaginations rather seamlessly, whereas Nana tries to demand everyone follow through with it, and likely to no avail outside of the maid cafe she worked at. At least she's a shortstack.
