Shigemura Tamotsu

Zekushiido (前駆しど) was the first victim of Death Gun. His real name is Shigemura Tamotsu. He was believed to killed by being shot through a TV at a bar, though cause of death is a result of heart failure. In reality, «Death Gun»'s "other half" injected Zekushido in real life with succinylcholine which causes the heart to stop.

Background
Winner of the «2nd Bullet of Bullets» tournament, he won due to obtaining a extremely rare gun, the XM29 assault rifle, and spreading misinformation about stat allocation to other players. He also opted to take a life sized model of a «Gun Gale Online» gun as his prize for winning the BoB instead of in-game currency. This eventually causes him to become one of Death Gun's targets.
