X-1999 (tv)

. FUUMA . Kamui's best friend turn worst enemy and mirror image. (figuratively) He can switch wildly from sweet and kind to violent hell raiser in an instant.

.KAZUKI. little is known about him. He seems very quite, and very obedient, reliable and violent.

Very strange pairing, but hard to deny.

POINT 1
There are very few scenes when Fuuma and Kazuki are together, and Kazuki isn't resting his head on Fuuma's knee, or lap. Or when Fuuma isn't rubbing his head, caressing his face, or going to any lengths to give him what he wants and visa versa.

POINT 2
At first glance it would seem that Kazuki sees Fuuma as a father figure. Maybe he does but that in itself is questionable.
Nataku: My father, you look like my father.
Fuuma: Nataku, what did your father call you?
Kazuki: Kazuki.
Fuuma: Kazuki...I'll call you that if it is your wish.
During this entire conversation, Kazuki is leaning against Fuuma's knee.

POINT 3
We get the impression that Kazuki was rather incestuous, and was in love with his father. If Kazuki does indeed see his father in Fuuma, we can draw our own conclusions as to why hebehaves the way he does around Fuuma. He is completely selfless when Fuuma's concerned. He is helpful, submissive, a a bit too affectionate, and very clingy.
Fuuma: Kazuki what do you wish for?
Kazuki: I don't know. But I feel that I should never leave your side.

POINT 4
Kazuki is SO selfless to the point where he deems his life completely in his tou-sama (Fuuma's) hands. Towards the end of the series, Fuuma is VERY badly hurt. Yet he asks.
Fuuma: Kazuki what do you wish for?
Kazuki: To always be with you.
Fuuma: Will you restore my body?
Kazuki: If that's your wish.
In a burst of Ki Kazuki explodes and literally uses his own flesh to restore Fuuma to full health again. Just like that, no questions asked. That's devotion!

Did I leave out anything? Let me know
