Actually, for Angel, he didn't care much whether the boy in the jug was a Star Servant or not. What he cared about was the mysterious objects.
It wasn't specifically about this Wish Book, but about seeing the system of mysterious objects behind the Wish Book.
Previously, when Angel heard about mysterious objects, he didn't feel much about them, because he hadn't seen them, and just listening couldn't reveal any beauty or ugliness.
But when he really laid eyes on a mysterious object, he was speechless with surprise.
The abilities recorded in the Wish Book are indeed not very powerful, but the varieties are so numerous! There are not only direct attacks, indirect attacks, control, support, but even the ability to produce potions!
And these abilities are all integrated through the Wish Book.
