The Mulan Who Can't Fight

Lana Hua, brain dead after an accident, is transported into 'Mulan's Adventure.' To be revived, she must clear this game. A 'death and rebirth loop' begins: she is insta-killed by the Rouran Khan. She tries escape methods in rebirth cycles, all ending in death. Flora informs her she is brain dead and must clear the game, forcing her to accept her mission.
