So, remember how most isekai main characters are pretty young, barring a few exceptions? And how, even if they are old, they nearly always get a young body for free?

It's because they are meant to battle monsters, not rheumathism. Also, it's tough to make a good story without bad decisions, and being wise is old peoples' entire thing. That, and most of them would rather just rest than jump around saving princesses.

Well, screw it.

This story would probably be about a young boy that found a passage to another world full of monsters, nobles and magic, if it wasn't about his neighbour, an unusually healthy old lady that will drag his ass back home, and have her fun while she is at it.

(Also, baby bunny on the cover completely unrelated, I just want you to look at this handsome beast.)
