Renji Magatsu is a childhood friend of Yuuya Daigo. He was a quiet withdrawn and sickly teenager always being physically abused by his drunkard father. Renji grew strongly attached to quotYuuchanquot because Daigo was his complete opposite strong both in body and mind and yet understood him sympathetic Yuuya was always willing to listen and support Renji. Renji Magatsu became a member of the Twelve Generals and as the Martial Fist was set to assassinate the Magami Five he naturally went against Yuuya Daigo drawing his old friend back to the place they used to hang out. With Renji calling him a traitor Yuuya couldn039t fight him instead running away.
