Sakamoto Tatsuma 181cm, 70kg, 18 years old One of the Four Heavenly Kings active as a Joui patriot. He is known as the Dragon of Katsurahama. He speaks with a distinct Tosa dialect. He has a characteristic way of laughing—a hearty, somewhat airheaded "Wahahaha!" He comes from a prominent merchant family in the Tosa Domain. He wears sunglasses almost every day. He loves space and often gazes at the night sky. He loves stars and looks up at the heavens every night. He has an incredibly optimistic personality. While he isn't always laughing, his expressions are actually quite varied, though often hidden behind his sunglasses. Fundamentally hopeful and bright, he possesses an ideal character that aims to move forward with others as a friend rather than standing above them. He values his friends and comrades above all else; he would sooner be abandoned himself than ever abandon a comrade, and he never turns his back on anyone, no matter how twisted they might be. Conversely, he can turn cold toward those who do abandon their allies.
