Is there a more cucked character in the Fate series?

I kind of wish HA had more of him

What's funny is Cu is fucking strong, one of the strongest servants in the franchise. Even with Command Seals holding him back he still managed to last half a day against Gilgamesh. And even though Caster is his weakest class, he was able to stomp through the 5th Holy Grail War as Caster and win.

how should tamamo punish my dick and balls for cheating on her?

He wins in Carnival Phantasm
