Owen: System! What should I do if my sister wants to destroy the world? !
System: That's why I asked you, as the elder brother, to take care of her~
Owen: (╬￣俣) It's good if she doesn't deal with me. Do I dare to deal with her? Thank you for lifting me up
Ou Li: Is my brother mentally ill? Do I look like the kind of person who wants to destroy the world? I just want to destroy humanity okay.
Thinking that he is the protagonist, he is actually cannon fodder in a rescue operation~
Motto: Please never be disappointed in the world
