I'm just wondering, how does a minor have enough money to fly to japan, find a place to stay, and also have the know-how to enroll in a Japanese high school all on her own...
What I really want to see is an isekai MC who is terrible at cooking. Wait, no, an MC who is decent at cooking and monologues about how great Japanese food is but then the otherworlders end up unfazed and are just like “meh, it was alright”
