Shion, originally from the Ogre tribe, survived the destruction of her village. She encountered Rimuru Tempest in the Jura Forest, attacking him due to a misunderstanding before mediation led her to join him. Rimuru named her "Shion," triggering her evolution into a Kijin—a more advanced ogre form. Standing roughly 170 cm tall, her appearance became less vicious, featuring long purple hair tied in a ponytail, a single obsidian horn, and a notably curvaceous figure. She adopted formal attire, typically a purple business suit over a light green shirt, though her horn remained prominent. Despite her cool, professional visual presentation, Shion's personality is emotionally impulsive and hot-headed, favoring brute-force solutions. Declaring herself Rimuru's "first secretary," she lacks actual secretarial skills, often relying on Shuna. Her actions frequently lack restraint, especially in cooking: her passionate efforts invariably produce toxic, purple, and sometimes sentient dishes due to her Unique Skill "Cook" warping reality. She remains unaware of these failures, believing her cooking improves. Shion competes intensely with Shuna and Diablo for Rimuru's attention, displaying aggressive jealousy towards others interested in him. Her devotion borders on reverential love, and she takes personal pride in Rimuru's achievements. Early insecurities about abandonment eased after pivotal experiences, including death and resurrection. During the Falmuth Kingdom's attack, Shion died protecting others, her horn shattered. Rimuru resurrected her during his ascension to Demon Lord, transforming her into an "Ogre Demon" or "War Spirit Demon." This granted near-immortality, immunity to pain, status effects, spiritual/physical attacks, and holy magic. Her Unique Skill "Cook" allowed unconventional applications like severing magical barriers. Post-resurrection, she commanded the revived villagers, the Yomigaeri squad, and her combat prowess surpassed Benimaru's in single combat. Her giant sword "Gourikimaru" was upgraded to harm spiritual entities. Later, intense emotion unlocked her sealed Ultimate Skill "King of Outrage (Susanoo)," enabling energy absorption and space-time manipulation. Her intuition sharpened due to a deeper connection with Rimuru. Shion led her personal army within the Jura-Tempest Federation and held titles among the Twelve Guardian Lords and Rimuru's "Big Four." She demonstrated unexpected wisdom, such as taming Dagruel's sons as students. In the film *Scarlet Bond*, she reunited with Hiiro, a fellow ogre survivor, and participated in resolving conflicts involving the Kingdom of Raja. Musically talented from shrine maiden guard training, she occasionally sang or played instruments with Shuna despite their rivalry. Her relationships centered on unwavering loyalty to Rimuru; she tolerated Diablo and respected Shuna as royalty unless competing for Rimuru's affection.
