Hanaori-san wa Tensei Shite mo Kenka ga Shitai

Hanaori-san wa Tensei Shite mo Kenka ga Shitai centers on Ryuusei Narukami, a shut-in NEET who spends his days in his room playing video games and drifting through the aimless, comfortable routine he built after reincarnating into modern Japan. Beneath that lazy everyday life lies a far stranger past: in another world, Ryuusei once ruled as a powerful Demon King. After losing that life, he wants nothing more than to enjoy this new existence on his own terms and protect the carefree peace he has found. That wish becomes difficult to keep when the person who ended his reign appears again. Meteor Hanaori, the Hero who once struck him down, has also been reincarnated into this world and now stands before him as a cute high school girl. Their reunion turns an old rivalry into a second life of awkward tension, unfinished business, and inevitable conflict. Forced back into society, Ryuusei becomes a teacher and ends up at Hanaori's school, where everyday encounters keep dragging their history back to the surface. The series builds its comedy and friction around former enemies who know each other too well, suggesting that even in a new world, some bonds are impossible to leave behind.
