I would help the magic girl, make some deal to use my normal pics and not the cringe ones, but even without that is a isekai world, who cares? At worst I would tell her to censor or change my name.
Seems like the alien meet MC when he was younger, the spreading his pics through space must be some alien tradition thing.
Red wanted to spread the pics too, but I think that is not related to him.
I don't get why witch tried to destroy the room with them inside now, she wanted the pics and probably needs MC alive, that part makes less and less sense, unless as I said before the storage had pictures of herself she have to hide above anything else.
This chapter is a snipe, but I think is a good one, this work is popular and the other translator split the first chapter in 2 parts and took 2 weeks in doing them, then dissapeared again, I checked again and there are like 14 raw chapters of this, not just 3.
