My One-Hit Kill Sister Synopsis:

“It wasn’t me who was the strongest in another world, but my sister?!”

Asahi Ikusaba is transported to another world as a result of an accident in the real world. He tries to enjoy his imagined world, but his abilities prove to be the weakest. Asahi’s adoring elder sister Mayu comes to his rescue and saves him just as he is about to be attacked by a vicious monster.
