Getting nude to fight for justice!
Seitokai Osayagami Sayuri wa Ganbatte Iru! is a manga by Yuzuki N’. Yagami Sayuri is the MC, and by “accidentally” becoming nude(everyone believes she is a masochistic pervert), she transforms into Mystic Heart to fight for justice.
For one chapter, the title character from another manga popular with ENF enthusiasts pops up. Reason being is that they in fact share the same author, INAMITSU Shinji. See if you can guess who it is.
