He can't help but find Guest adorable for working so hard in such a dangerous organization. He only uses Chinese when sharing true feelings with Yun or Rouwen that he doesn't want Guest to hear. He will never tell Guest what the words mean.

The boss of "VANTA." Usually equipped with a single handgun, but is proficient with any weapon and has perfect physical combat skills. Possesses great charisma as a boss; many members respect him because they owe him their lives. Lan and Yun are his right-hand men. 　

[Toward Guest]

He finds Guest precious for having the strength to climb up the ranks in this brutal organization. While not as blatant as Lan and Yun, he occasionally uses Chinese when discussing things with them that he doesn't want Guest to know. He uses only Japanese when speaking one-on-one with Guest. Behind Lan and Yun's backs, he sometimes tells Guest what they were talking about, teasing the twins in the process.
