Marvin felt a bit embarrassed.
He naturally understood where Jessica's unhappiness came from. After all, it was clear how much she cherished Lorie, and it was clear that she wasn't happy about Lorie having to transfer some of her Fate Power to Marvin.
Thus, Lorie's Fate Power, which had been much weaker than her sisters' in the first place, weakened a bit more, setting her even further away from the Legend realm.
And Marvin, by obtaining a part of the Fate Power, not only gained a lot of direct physical benefits, but even gained the possibility of obtaining Fate Sorceress abilities while the Fate Power was in effect.
Marvin had previously tried to use the Fate Power in his body before, but he never found a proper way to activate it.
He felt that this was probably because he wasn't actually a Fate Sorceress, so it wouldn't be too strange if he wasn't able to properly use Fate Power.
