    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 Chapter 99.[1],

    Kei Tachikawa (()()(かわ) (けい), Tachikawa Kei ?) 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[edit | edit source]

    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[edit | edit source]

    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 according to Jin, it is extremely unusual for Tachikawa to lose his composure in combat.[7] however 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 duels, 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.[1] He is harsh towards Murakami, possibly because he has high expectations for the prodigy.[8]

    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.[9] 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 to win enough.[10]

    Quotes[edit | edit source]

    • (To Yūichi Jin) "3 weeks until official enlistment day. During that time, I'll definitely defeat you, and recover the Black Trigger." [11]
    • (During Aftokrator's invasion.) "Right, right. Let's finish this before lunch." [12]
    • (During Tamakoma Second's second rank war) "The strength of your feelings doesn’t matter. Power, strategy, and luck are what decide a battle. […] Only when two opponents are closely matched does passion really make a difference." [1]
    • (During Tamakoma Second's second rank war) "Don't get me wrong, I love passionate battles. But, if you attribute the outcome of the match to passion, you might as well be saying that the loser just didn't want it enough." [10]
    • (About Suzunari First) "Murakami and Taichi would come to protect Kuruma no matter what. That's how Suzunari First fights as a Squad." [13]
    • (About Osamu Mikumo) "Mikumo's aim from the very start was to deplete Nasu's trion. On top of having Amatori escape to reduce the risk of being destroyed, he went in for another point. Now I see. He is really a ruthless guy." [14]
    • (To Takeru Yuiga) "Alright, listen. I'm gonna say something good. Look at our emblem. There are three swords, right? This first one is me, the second one represents Izumi, and the last one is... My second sword. In other words, you're still a novice, so no getting puffed up. [...] Kunichika, you're the crescent moon on the back." [15]

    Trivia[edit | edit source]

    • "Kei" (慶) means "to congratulate, to celebrate", while "Tachikawa" (太刀川) means "Tachi River".
    • He likes Udon, Mochi (Japanese rice cake), croquettes and winning Rank Wars.[3]
    • he has done a lot of stupid things outside of battle[16]:
      • He read the word "Danger" [deyn-jer] as "Dangah".
      • He once thought a computer was broken when it was just unplugged.
      • He only ate the dried fruit on a fruit granola bar.
    • When asked in a Q&A if the reason why Tachikawa's eyes resemble a grid is because, "he burned the mesh for grilling his beloved mochi into his eyes", Ashihara said that's probably the reason.[17]
