My One-Hit Kill Sister

Asahi is your average game otaku. Just when he thinks his life is over, he gets another chance in a world that seems just like an RPG! But he doesn't have the cheat skills that isekai heroes usually have. Instead, someone familiar swoops in to save.

Asahi takes on a quest to gather mushrooms.

Asahi goes to the Guild with the thought of forming a party with other people.

Asahi and Maya realise that they are missing something essential in the life of every adventurer.

A new dungeon entrance has been discovered! Tanya asks Asahi to explore it to see if it's safe. If it is, it will be opened up to all adventurers of every rank. Asahi is excited about taking on a quest by himself, but, alas, it is not to be.

Asahi bumps into a strange girl on the street.
