Kuku, Bring it on. I'll crush that confidence of your with my one fist
- —Walter's intro quote
A built tall and muscular man wearing a black suit and sunglasses with a smoking habit.
Once Kilika's lover and the expected successor of the Taito Style (泰斗流 Taito-ryuu?). However, Master Ryuuga decides to give the successor seat to the other candidate Zane instead. After hearing this, Walter that can't accept this fact asked Ryuuga to let him fight against Zane. But Ryuuga said Zane will just let Walter win unconsciously both in martial arts and woman. Walter starts to go mad and so Ryuuga chose to fight him in place of Zane and ultimately gets killed by his own disciple.
Unbeknownst to him, Ryuuga was terminally ill at the time, Ryuuga's intention all along was to teach Walter and Zane the way of life of a martial artist by choosing to die by the hand of his number one disciple, Walter.
