Ryo Kanzaki

Ryo Kanzaki is one of the antagonists of Crossroads of Destiny. His Vanguard circle is rust red.

Personality
Ryo doesn't have much of a personality. He is a follower, rather than a leader, and like Reiji, he is loudmouthed and easily angered.

Crossroads of Destiny
It is unknown when Ryo first met Reiji, Asahi, and Jun, but it is possible that they met while Reiji ran the underground fight circuit. Ever since, Ryo has been extremely devoted to Reiji, even as Reiji became more and more distant from his friends. It was during this time in the underground fight circuit that Ryo began to refer to Reiji as Reiji-sama.

Some time later, as Reiji pursued a career as a professional Vanguard fighter, Ryo became his manager.

Reiji Midorihara
As stated earlier, Ryo is extremely devoted to Reiji. A few fellow Vanguard fighters, among them Agrise Attorns, have suspected that Ryo may harbor romantic feelings for Reiji, suspicions that Ryo always vehemently denies and that Reiji never hears. Ryo refers to Reiji as Reiji-sama and to himself as the Second Vanguard, perhaps referring to his own aspirations in the professional circuit.

Agrise Attorns
Ryo and Agrise do not get along. While the exact circumstances of their relationship are not known, he is shown to have known Agrise previously, and greatly admires her, to the point of developing a rather strange obsession with Agrise. Ryo often uses insect metaphors to try (and fail) to win her heart. He refers to her as Chōchō-chan (Butterfly-chan), while she refers to him as Teizoku-san (Nasty-san).

Makoto Sakaki
Ryo and Makoto meet on their way to the Tournament of Champions. Ryo despises Makoto for his humiliating defeat of Reiji, which Ryo suspects was due to cheating. Ryo tries and fails to defeat Makoto to prove this point and develops a rivalry with Makoto.

Deck
Ryo uses a Megacolony deck based on the Machinings archetype. His ace, Machining Warsickle, is used to deliver a punishing blow to his opponent, with its ability to gain Power for each of his opponent's rested rear-guards, and its ability to prevent the opponent's vanguard from standing at the start of the next turn.

Ryo plays very aggressively, usually utilizing the Protect II gift to give his rear-guards a mini-Force boost. He uses the Machinings ability to add grade 3s to the hand to ensure he has plenty of hard hitting attacks.
