He is the Dude With Whom You Do Not Mess, I suspect. Looks like Santa’s biker-gang brother. Actually, it’s Takeuchi Sukune, and if I understand the strangely translated pages correctly, he was a quasi-mythical figure who lived to be 280 years old. Or – more likely  - it’s the other Takeuchi Sukune, a minister who served four emperors, and died in 1861 at the age of 63.

Still wouldn’t mess with him.
