Sakura "Sakura-chan" Ise works as a stoker in the Harekaze’s engineering division, her expertise honed in machinery maintenance and operations. She sports reddish hair tied in a left-sided ponytail with right-swept bangs, accentuated by bright blue eyes, and adheres strictly to the standard uniform without alterations. Born November 21 under Scorpio in Miura District, Kanagawa Prefecture, she stands 163 cm tall with blood type B. Her mechanical aptitude stems from training under a family friend of her grandfather, skills she diligently applies aboard the Harekaze. She forms part of a tight-knit engineering quartet notorious for gossip and card games during downtime, often playing mahjong—a noted hobby—while trading rumors. Sakura exudes a sensual charm, occasionally veering into unintentional playful eroticism. She once boasted the most striking figure among her peers until Wilhelmina’s arrival, whose more generous bust sparked visible frustration. Academically inclined toward science, particularly physics, she nonetheless struggles with Japanese language studies. Her preferences lean toward savory okonomiyaki, though she recoils at okra’s slimy texture. Conversations frequently feature her quirky refrain, “up-down left-right.” Documented sources outline no further character evolution or expanded backstory in additional media.
