He also acts like Jin, they have a similar way of thinking, which makes him unliked by Miwa. Despite that, he's quite friendly outside of the battlefield. He likes to joke around, just like Jin. He has strong views of strength, seeing it as a product of strategy and strength. But unlike Jin, Tachikawa is very dedicated in ending a battle quickly and perfectly. Similar to a samurai he keeps a firm posture, and a habitual technique to persistently execute devastating blows. He can be seen as aggressive when fighting, due to the destruction of city property and sacrifice of a squad member. Moreover, being blind due to his focus, he is unable to have a larger viewpoint of the situation and turn the battle into his favor.
