Kei Tachikawa/Abilities

Being the No. 1 Attacker and overall number one he's one of the strongest agents currently in Border. This is shown when he effortlessly cut an Ilgar apart in one swing while Kitora struggled to even scratch the Ilgar. More proof of his strength is that he was the agent that had killed the most Rabbits on his own, eleven, despite Replica stating that an A-rank agent would have trouble with one Rabbit if they were on their own. His dual-wielding  Kogetsu style was passed down to him from Shinoda. Usami  stated that Tachikawa is the superior swordsman between  Jin  and him, although she also noted taht their match have been ties since the latter began using Scorpion. While in battle he prefers to fight head-on, he can also be analytical, as demonstrated during his commentary and when he defeated Gatlin with Kirie's help. Generally, he is unperturbable in battle. By using Grasshopper to get close to opponents that Senkū alone cannot reach, his range matches that of a Shooter despite him being an Attacker.
