異世界に転移して勇者になった森下大樹は、みごと魔王を打倒して日本に戻ってきた。 大樹は身につけた力を隠しながら、平穏な日々を満喫していたが……。
この現代では人知れず妖魔や能力者が跋扈する、(今時珍しい)学園異能バトルっぽい裏の世界が広がっていたのだ!!
これは異世界帰りの最強勇者が現代で無双していく物語である!
Morishita Taiju was transported into another world and became a hero, after wonderfully defeating the Demon Lord, he has returned to Japan. He was satisfied with his peaceful days as he hid his power, but… Hidden yokai and people with powers start to rampage, and the (rare nowadays) academy power battle-ish hidden world unfolds!! And Now He Trains Beautiful Warriors Using Superpowers!?
tl;dr: Isekai returner retains his OP skills after returning to Earth; discovers that Earth has more supernatural stuff going on than he expected. Gets dragged into various shenanigans, mostly via helping beautiful women around him.
