Background / History

Sakura infiltrated Mobius's laboratory while Bronya was absent from the immediate area, moving through its corridors without making a sound. Bronya intercepted her, recognizing her as the assassin known as “Forget-me-not.” Sakura fought with a masked identity and attempted to retreat when she realized the difference in their strength. Her reason for refusing to yield was Rin, her younger sister, whom she was determined to protect. 80

Bronya pursued Sakura outside the laboratory, disarmed her, and exposed her identity. By threatening to reveal Sakura's life as a killer to Rin, Bronya forced Sakura into negotiations; Sakura agreed to cooperate on the condition that Rin would not be involved. Mobius subsequently negotiated with Sakura, who joined the laboratory. 81

Sakura later fought alongside the Flame-Chasers. She participated in a chaotic sparring match against Byakuya and other combatants, and later used her assassin's swordsmanship and Divine Keys against the Rock Herrscher. 92 103

When Rin manifested as the twelfth Herrscher, Sakura joined Mobius's laboratory in supervising her within the Elysian Realm. Although Sakura struggled with Rin's transformation, she ultimately accepted Rin's reassurance and accompanied her through the realm. 113

After Rin's consciousness was sealed in a Black Box, Sakura guarded it in silence. She joined the expedition against Finality, deploying Seven Thunders of Retribution in sniper-rifle form and using its zeroth-rated power. Following the failed campaign, she continued to hold onto hope for Rin's recovery. 116 117

Personality

Sakura is quiet, cautious, and resolute. As an assassin, she avoids unnecessary words during combat to reduce the risk of exposing herself. Even after being outmatched by Bronya, she continued fighting and attempting to escape rather than surrender. 80

Her strongest motivation is protecting Rin. Sakura's fear of having her identity exposed did not outweigh her willingness to threaten Bronya if Rin were endangered. 81 After Rin became a Herrscher, Sakura initially found the situation painful but composed herself quickly and chose to remain by her sister's side. 113 117
