My One-Hit Kill Sister Synopsis:
“It wasn’t me who was the strongest in another world, but my sister?!”
As a result of an accident in the real world, Asahi Ikusaba is transported to another world. He tries to enjoy his imagined world, but his abilities are the most limited. Mayu, Asahi’s adoring elder sister, comes to his rescue just as he is about to be attacked by a vicious monster.
Mayu, who was pursuing Asahi’s love, ended up in the same world as him, with the most powerful abilities and cheat skills. The fantasy story begins with the strongest elder sister having a brother complex and the youngest brother having the most flaws.
