Kei Tachikawa

This article is about the character. For other uses, see Kei Tachikawa (disambiguation).

"Only when two opponents are closely matched does passion really make a difference. If victory was decided by the strength of a person's emotions... There's no way I'd ever be No. 1."

- Kei Tachikawa during Tamakoma Second's second rank war in Nasu Squad 4.

Kei Tachikawa is the captain of Tachikawa Squad and both the No. 1 Attacker and the No. 1 agent overall in Border. Due to his actions, he was an antagonist of the Black Trigger Capture Arc, but later becomes a supporting character.

Appearance
Tachikawa has medium length, wavy brown hair (gray in anime). His brown (gray in anime) eyes have an odd crosshatched design.

In his trion body he wears a black trench coat, adorned with red pinstripes. The Squad emblem takes place on his shoulders. He also wears black pants and black boots.

Personality
Tachikawa is an arrogant person and as a result has carelessness, risk-taking and underestimating the enemy as his flaws. Also, he tends to be in his mind a lot and becomes anxious when an opponent is surprisingly more difficult. But by being in his mind he analyses the situation with the information that he acquires in battle.

He also acts like Jin, as they have a similar way of thinking, which makes him disliked 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 to 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 the 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.

However, this is good for 1v1s, because of his habit to lock onto an enemy. In summary, when Kei Tachikawa uses his trion body, and wields his Kogetsu, resilient, powerful, precise, attentive, disciplined, logical, humorous, selective, observant, helpful, confident, reliable, and controlled are a few words that describe his personality. He is harsh towards Murakami, possibly because he has high expectations for the prodigy.

Sometimes, he might come off as insensitive, such as saying that feelings don't matter in battle as he would never be the number 1 in Border if that was the case. However, he later corrects himself by saying that he does like battles with emotion, but feels attributing the results to emotions is like saying the loser didn't want enough to win.
