I can’t stop laughing when I think that if Isabella and Ursch were to team up in a fight, Isabella would likely (willingly) become a meat shield for him. With that much HP (and perhaps it will rise in the future), I suspect that she will no-sell pretty much anything thrown at her. And she will fight everything under the heaven and above if it is for her Ursch. She will pick a fight with a god if she must.
And my little yandere Ursch-kun is just the cutest!!!! Love can be a heavy burden when it is unwanted, but it is clear that Isabella is as much into him as he is into her. Seeing the always calm Ursch being surprised and shy make me squeal so much.
Another thing, I would say that while Ursch is OP, it’s perhaps not surprising considering that in the game he was pretty much one-man shop. He ran the store by himself, replenish his stocks by making them from the materials he hunted himself. His store also seems to carry many types of products.
