Soshiro Hoshina

He belongs to a family of swordsmen who for centuries were part of the Defense Forces against Kaiju, but with technological advancements, the creation of firearms, and the increasing size of the Kaiju that appeared, swords ceased to be used to exterminate them. His father, who had retired from killing Kaiju, asked him to give up his dream of joining the Defense Forces. Everyone told him to give up, that "the age of swords is over," but he still didn't stop training with his sword, managing to enter the Defense Forces, finding his place in the third division as vice-captain, alongside Mina Ashiro, the captain of the third division. He complements her, since she only fights with firearms and has no skill with bladed weapons, while Hoshina only fights with swords and has no skill with firearms. Over time, he also develops a rivalry with the captain of the first division, Gen Narumi.

He is a powerful fighter, capable of fighting on par with Kaiju No. 10. While his skill set puts him at a disadvantage against large Kaiju, Soshiro's proficiency in defeating small to medium-sized Kaiju in battle surpasses that of the First Division captain, "Japan's strongest anti-Kaiju fighter," Gen Narumi. Soshiro can utilize a significant amount of his combat suit's power. His maximum unleashed combat power in a normal combat suit is 92%, and 100% when using the numbered Kaiju suit.
