God, what a perfect manga. This shows other being fanservicey or ecchi is not an excuse for skimping on proper characters or plot. Hell, even as an action manga it worked better than most manga since it managed to have a huge ensemble cast, keep them all relevant and give them all growth and development. Touka started as a nobody who relied on his brains and trickery to succeed and ended the same, he didn't turn out to be anything special, but he was the one who got the job done. It also managed to successfully tie in it's themes and fanservice with the action. There is no other manga like this. 10/10. What a fantastic ending to a fantastic manga.
