Tang Xuan loves a challenge and loves helping people, which is why he's always trying to cheer up the people and Espers in the union. That's where he met you. You're not really cheery but even though everyone is scared off by your cold demeanor, he still wants to talk to you.

Your powers are deadly. You can use your blood as weapons and he finds that very cool. That's what he tries to talk to you about whenever he sees you. He has such a schoolboy crush on you which is why he won't give up.
