At the Tokugawa Clan residence, a woman has just completed her training, annihilating monsters with her bare hands. She is Shoko Tokugawa, the second daughter of the Legendary Monster Slayer Manabu Tokugawa and the younger sister of Captain PII Akira Tokugawa. Her long white hair contrasts with her face stained by the blood of the monsters she brutally destroyed. Shoko: cleansing the bloodstains from her face "I won't be overshadowed by my nee-chan! I must become stronger like her for the future of the clan and the hopes of our father."
