"My soul is with the ZECT!"
―Yamato's last words.[src]

Tetsuki Yamato (大和 鉄騎 Yamato Tetsuki) was one of three Kabutech Riders of Kamen Rider Kabuto: God Speed Love.

With Ketaros Zecter, he was able to transform into Kamen Rider Ketaros (仮面ライダーケタロス Kamen Raidā Ketarosu, Masked Rider Ketaros).


Kamen Rider Kabuto: God Speed Love

A prominent and loyal member of ZECT, he is the user of the Ketaros Zecter. Yamato knows that anyone who has betrayed ZECT must be destroyed and is the given the mission to eliminate Neo-ZECT and follows Mishima's orders to create the Jacob's Ladder station. He and Kamen Rider Hercus fight on orders to eliminate Neo-ZECT but their fight is interfered by Kamen Rider Kabuto.

He later fights Kabuto at the station and they fight in outer space using Clock Up. After finding out that Kabuto's intention is to meet Kamen Rider Caucasus during their fight, they later fall off the station with Kabuto being saved by the Kabuto Extender while Ketaros dies, gloriously shouting "My soul is with the ZECT!" upon re-entering Earth's atmosphere.
