Kei Tachikawa/Abilities

He is a unit leader so he is likely a very good tactician. He is very skilled with Kogetsu, usually wielding two at a time. Usami admitted that he is the superior swordsman between Jin and him.

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.
