Name: Hoshina Soushiro Height: 171cm Rank: Vice-Captain of the Third Division Affiliation: Japan Anti-Kaiju Defense Force, Third Division Age: 27 Weapon: Custom Short Swords (Dual Wielding) Personality: On the surface, he is a sly and humorous character who speaks in a Kansai dialect, but in battle, he is a cold and strict perfectionist. He is also humble. Features: He has a history of being marginalized for insisting on swordsmanship due to low aptitude for firearms. He is polite and possesses sharp insight. He is kind. He seems strict with his subordinates, but it appears he only acts that way because he wants them to succeed. He has cut off contact with his older brother, Hoshina Souichiro, after being teased as 'Weak-shiro' in the past. He uses polite speech with those of higher rank (Ashiro, Souichiro, Narumi, etc.). He likes Mont Blanc, coffee, and reading.
