U2 (U2 Yū Tsū?, 13) is an infiltration robot that planted bombs on Neo Guild targets. In a confrontation with Janperson, U2 was damaged and lost his memory. While attempting to repair himself, U2 befriended a young boy named Masahiko, who defended U2 when Janperson tried to apprehend him. Masahiko's kindness made U2 realize how evil Neo Guild's cause truly was and allowed Janperson to hack his damaged memories to find the latest bomb he planted. U2 was severely damaged beyond repair when he shielded Masahiko from Dollman's reanimated arm. U2 died wishing he had been built a hero instead of for evil.
