Rikuou saved Kudou from freezing on the street at Christmas. Both of them as far as I know are runaways (Though it's never mentioned why just that they did)... They both live above the drug store they work, the mysterious Manager of the store, Kakei (Tall blond) keeps sending them on small jobs for him. He also has a *caughes* lover? Saiga, (Tallist Black hair) who never takes his sun glasses off and when not groping anyone blond is sleeping.
Kudou has some kind of ESP, he see things when he touches stuff or someone, based around emotions, he keeps seeing a girl in his visions and this turns out to be someone Rikuou knew and is looking for, after such encounters he normal passes out. I think his ESP is the reason he ran away from home?... He keeps saying he need's money, and you find out it so he can move out and live by himself, he keeps calling Rikuou names and on the outside he hates him, but we know there is something else going on that he just doesn't want to admit to himself.
Rikuou, though his cold and cool outer image is always there for Kudou when ever he's in trouble, and Hudou can also see though his eyes when in physical contact. Rikuou also possess some kind of ESP, he can brake things or move things with his mind, but again not much is said.
Kakei is a mystery also, at the end of the manga you find out that he has the ability to see into the future, and he seems to know more than he's letting on. The why and where for of him sending the two 17 year olds on little ESP missions is a mystery also, though Saiga seems to know what's going on.
This is Clamp at their finest, The story skips along in a light hearted mood with Clamps unmistakable dark undertones, but your laughing or biting your lip with this one, just the right mix of light and dark that isn't as oppressive as Tokyo Babylon, X or even R,G,Veda. nor is it kiddy-fied as Cardcaptor Sakura. I've fallen in-love with this one volume. Everything about it is just RIGHT...
This is a MUST for anyone who loves Clamp, or even if you don't!
