Taiyang Xiao Long

Taiyang Xiao Long (太阳小龙 [Simplified] 太陽小龍 [Traditional], literally: Sun Little-Dragon) is the father of Yang Xiao Long and Ruby Rose. He is mentioned to be a teacher at Signal Academy on the island of Patch where the girls grew up.

Personality
Taiyang is said to be a bit overprotective by both of his daughters, yet still open and caring. His attitude towards helping others in need was shared between his spouses and was passed along to his children too.

He appears to have an eccentric side, as he is stated to do things like send the family pet Zwei through the mail all the time.
