Koume wears a pink jumpsuit, but never acts feminine. She is loud, brash and aggressive due to her stint in the Japan Self-Defense Forces. She was discharged by the SDF and transferred to the TAC as a result of insubordination. Her philosophy is based on the "bigger gun" theory and uses her military mind and muscle to destroy the Aragami. Despite her tough exterior, she is a vulnerable woman who wants to give her love. She has a soft spot for puppies, enjoys playing matchmaker to Momiji and Kusanagi.
The stereotypical computer nerd, Yaegashi does computer analogy for the TAC. On off days, he enjoys hentai games on his computer. He also has a program that pinpoints the Aragami's weak points and attacks, but it doubles as a program to predict what animal would appear on Momiji's panties. He has a love/hate relationship with Kome through most of the series.
Blueno started his own bar about five years ago in the backstreets of Water Seven, calling it simply "Blueno's Bar." It was in a seedy side of town, where vagrants and ne'erdowells coalesced, but he at least acted happy. In truth, alas, it wasn't so: Blueno was a covert agent of the government's sent to steal the plans to an Ancient Weapon. It was in this fashion that Blueno met the supposed hidden king of Water Seven, Franky, and the two struck up a friendship of sorts. Again, it wasn't really so, but that friendship had some repercussions later on. Blueno ate the Doa Doa no Mi (Door Door Fruit) which allows him to create doors on any surface. He has even created "air doors", doors in the air itself, which lead to what seems to be another dimension. Blueno is also able to create doors on people, and did so to Luffy's face, causing it to spin like a revolving door. Blueno's tekkai seems to be the one of the more powerful ones of the group, and he was the first to reveal any variations of the move. Source: http://arlongpark.net/
