"Please remember that what I sell is not a jar, but the hope that can change your destiny." This is what I tell my customers in every small world I go to.
Notes: 1. The concept of the jar is borrowed from the novel Qidian Sword Rune Da Da.
2. The character is likely to be OOC and may significantly change the original world line.
3. As for the emotional line, it has not been decided yet.
4. The world is tentatively determined: Fumino, Demon Slayer, Naruto, One Piece, Xeno, etc. If there is anything else you want to see, tell me in the comments.
