The deuteragonist and official mascot of Choukou Taisen Escalation Heroines. Yuno is a close associate of Ikusabe Tokisada, who traveled with him into the past to prevent the ruinous future they hail from. She also "trained" (that is, had sex with) Tokisada in preparation for the challenges ahead.
While not a playable character, she does become one of two leaders of DIE-BEAT, alongside Kouenji Sayuka.
