Luca can't fight, but he is definitely the most important person in Gao Yi's team, bar none.
In some ways, Luca is even more important than Gao Yi, although it's not always obvious, being unobtrusive doesn't mean he's not important.
Why? Because Luca is in charge of the money.
Put it this way, Gao Yi is the soul of the Garden, or maybe the soul of the Warhammer, anyway, the name is secondary, the point is Gao Yi is the soul of their gang, there's no doubt about that.
But Luca is the cerebellum of the Garden.
Not the brain, but the cerebellum, or maybe it would be better understood as the brain stem, which ensures that the untrustworthy collective of the Garden can function properly.
