The only one Baron trusts/ The only one Baron calls "friend".
He's the second to arrive in this pocket dimension, because Baron's pupil was afraid of what he could have done if he discovered what he did.
Like his name suggests, he is a very strong man, throwing him into this place, was a very big mistake, because he gave him the reason to train even more harder than before.
And so, like Baron, he can't wait for the day to whop his ass.
After Riju Kida's arrival, he established a "Master and Apprentice" relationship with him, and he began to train the boy to help him fulfill his dream.
He's a man who speaks with his fists, a muscle-head that won't listen to everyone but the one he respects, except when people make fun of him, when that happens, his ears are widely open.
Like Baron, he's a narcissist too, and he likes to arm-wrestle everyone.
Other than being strong...
He's really stupid.
