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 rabbits, despite Replica stating that an A-rank agent would have trouble with one Rabbit if they were on their own. He is very skilled with  Kogetsu, usually wielding two at a time. Usami  admitted that he is the superior swordsman between  Jin  and him, although it should be noted 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.
