Shion, the Kijin secretary from That Time I Got Reincarnated as a Slime, has charmed millions with her Oni strength, hopeless cooking, and fanatical devotion to Rimuru. From vengeful ogre survivor to Wicked Oni powerhouse, Shion is the perfect storm of loyalty and chaos.
Shiion (紫苑) is a major supporting character in Fuse’s That Time I Got Reincarnated as a Slime (manga 2015–present, anime 2018–present). Introduced in chapter 12 and episode 5, she’s a Kijin and Rimuru’s primary secretary, evolving from ogre to Wicked Oni after the Falmuth revival.
An ogre from the Jura Forest, Shion is among the third group named by Rimuru after the Orc Disaster, evolving into a Kijin and becoming his secretary. Her death during the Falmuth invasion fuels Rimuru’s Demon Lord ascension — she’s revived via fusion, emerging as a Wicked Oni.
Her chaotic rise:
Ogre Fusion: Named, gains Oni strength, but cooking kills (literally).
Falmuth War: Dies protecting Rimuru, revived as Wicked Oni with enhanced power.
Walpurgis Arc: Performs as unwavering secretary, fights alongside Kijin.
Eastern Empire Arc (2025): Oni King fusion — leads charge against imperial yokai, performs in Unital Ring as idol fusion for morale.
sion’s vow: “Rimuru-sama! I’ll crush anyone who dares harm you… and cook for you later!”

Shion wields strength as a storm:

Personality Traits
Sion is dense, devoted, and hilariously destructive:
Fanatic Worship – “Rimuru-sama!” — sees him as perfect god, ignores flaws.
Hopeless Cook – Meals kill (literally); Rimuru bans her from kitchen.
Rage Mode – Overprotective, crushes threats to Tempest with joy.
Growth Arc – From vengeful ogre to wise secretary (still dense about romance).
