This manga is amazing! There's absoulutely nothing I dislike about it! It's incredibly hilarious mixed with amazing action scenes, sweet romance, and touching scenes of angst. I'm not really into drama, but this added just the write blend to keep me interest throughout the whole series. I've read this manga at least ten times (truly) and I still haven't gotten tired of it.
Tsukasa and Ryuji make such an awesome team as both lovers and fighters. You couldn't ask for a better pairing.
