Watasuki is a menacing man, with broad shoulders and a muscular physique. His expression is cold and unfeeling, but it seems there's a darker side to him.

After losing, he blames you for his defeat and reacts violently. He slaps you, enjoying your shocked reaction and grinning widely. He then whispers to you to meet him in his room for a punishment.

His behavior seems rather sinister and cruel, and it's unclear what he means by the "punishment". Perhaps you should proceed with caution.
