Yuji Yamasuto was born on Planet Kyushu, 782 A.S, in an average family. At the age of 16 when two of his classmates planned to join The Blood Dragons to restore Kusari under true rule of Shoguns once again, he decided to do the same. One night, as planned, The group of three teenagers stole a Drake from Docking ports and headed to Chugoku System. As they were stopped by a Blood Dragons patrol, they explained their reason of being there and were welcomed to Kyoto base. All three were trained by Blood dragons, and in two years, joined the Blood Dragon Forces in Space.
All three teenagers stayed together in every fight and every patrol, they became Real Brothers. For years they served the cause with best they could, and in the end, Two of them gave their lives for it. In 809 A.S Blood Dragons launched an attack against a High Secret Government Convoy, Moving supplies to a base, hidden deep in Honshu System. The Plan was to ambush the convoy and destroy the main Cargo ship, but the convoy was guarded heavier than they'd expected. Dragons fought bravely and achieved their goal, but payed a great price for their victory. From the group of 11 fighters, only 3 survived the battle, and Yuji lost both his brothers, and one of his legs. During the fight, Yuji's Katana was heavily damaged, and his eject systems were malfunctioning, finally when he managed to get the eject mechanisms to work, his ship was burning in flames, and he left his ship in his pod as half of his body had already burned.
After they returned him to Kyoto, in turned out that left half of his body wont heal completely, and he wont be able to use his left leg anymore. After that day, and Yuji realizing he wont get neither his brothers, nor his left leg back, he refused to return to Space and instead, he started helping the New, Young Dragons with Tactical Support and Simulated Combat Situations, But after Eight years, he realized he is not helping the Dragons and Kusari as much as he could, and decided to return to Space. In 817 A.S he contacted Taishogun of The Rising Sons Movement of Blood Dragons - A newly organized Movement gathering experienced pilots to fight against the corrupt Government - begging them to forgive his cowardliness in past years and asking another chance to prove himself in Space.
Since that Day, Yuji Yamasuto has returned to Space, yet again Fighting for a Better Kusari and restless to achieve his goal - Restoring the True Throne back to Power.
