Lisa Morisaki, the late wife of Ryuji Morisaki, lived constrained by a chronic illness that confined her to bed for long stretches. In 1963, during Ryuji’s absence on a mission, she collapsed while reaching for medication, an accident that proved fatal. Her death shattered her husband, igniting his obsessive decade-long pursuit to revive her through Agartha’s mythical realm. Her final words—a plea for Ryuji to embrace life fully after her passing—haunted him, clashing violently with his refusal to let go. Her demise anchors Ryuji’s relentless quest for the Gate of Life and Death. In the narrative’s climax, he briefly channels her soul into Asuna Watase, a companion, sacrificing his eye to complete the transfer. The resurrection unravels when Shin destroys the clavis crystal, dissolving the connection. Before fading from Asuna’s body, Lisa reiterates her dying wish, imploring Ryuji to seek fulfillment beyond her and accept death’s inevitability. Her surname, Morisaki, derives from the Japanese characters for “forest” (森) and “cape” (崎). No other records expand on her life or media appearances beyond these events.
