Sword Art Online Alternative: Gun Gale Online

Synopsis

Helped out by SHINC's Eva, who forces MMTM to retreat, Llenn explains the situation concerning Pitohui to her. Following this, Eva leads SHINC in an assault against PM4, using one of their dead teammate's body as a pedestal an anti-tank rifle to destroy M's shield. This provides Llenn with the opportunity to make a beeline towards Pitohui, only for another team's sniper to hit her first, bringing her down to a sliver of health. With Pitohui passed out and MMTM closing in on their location, the rest of PM4 sacrifice themselves to protect Pitohui before she regains consciousness.
