Kei Tachikawa/Abilities

He is a Unit leader so he is probably a very good tactician. He is very skilled with Kogetsu, usually wielding two Kogetsus at a time. According to himself, in true Swordsmanship he is stronger than Yūichi. Which might mean he is stronger than Yucihi jin with his scorpion trigger(No fujin)

Being the number one attacker and overall number one he's one of the strongest agents currently in border. This is shown when he effortlessly cuts 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. While it was said that an A-rank agent would have trouble with one Rabbit if they were on their own.
