Background and History

Shido lives with his younger sister Kotori, who commands Fraxinus. After meeting Lingmeng, he approaches the Spirit later named Tohka despite the danger she poses. Her isolation strengthens his resolve to save her, and he begins working with Ratatoskr to reach Spirits through trust rather than force 7 12 17 20.

Shido can seal a Spirit’s power when their feelings for him are strong enough. He seals Tohka’s and Lingmeng’s powers, though Lingmeng retains enough of her immense reserves to keep using her abilities. Sealed power can flow back to a Spirit if her emotions become unstable 57 65 68 77.

His efforts to rescue Yoshino nearly kill him: he walks through her ice barrier without protection because Spirit power would strengthen it and prevent his healing from working inside. Lingmeng saves him from a fatal spike, and the two return Yoshino’s puppet. Yoshino then willingly kisses Shido, sealing her power 93 94 95.

Shido later seals Kotori’s power and recovers memories connected to her becoming a Spirit five years earlier. When Origami continues to target the Spirit Efreet, he demonstrates Kotori’s healing flames and offers himself as her target instead 192.

On Orumi Island, Shido first summons Lingmeng’s Angel, Elemental Spirit, while trying to protect Tohka from Ellen. He later summons Tohka’s Sandalphon to halt Kaguya and Yuzuru’s battle, then proposes sealing both sisters’ powers so neither has to disappear. They are subsequently sealed 271 276 277 278 282.

During the rescue at DEM’s Japan Branch, Shido summons Sandalphon again and learns to combine it with a limited use of Elemental Spirit. Later, faced with Inverse Spirits, he puts aside his weapon to restore Tohka and Yoshino through their memories and affection, and uses Elemental Spirit’s time power to separate the merged Yamai sisters 383 384 419.

Personality

Shido is considerate and often awkward under romantic attention. He cooks for others, tries to reassure frightened Spirits, and becomes flustered when friends or Fraxinus staff tease him 26 82 164. He avoids killing even when fighting Wizards 384.

His determination can become reckless. He knowingly enters Yoshino’s lethal barrier and repeatedly fights opponents stronger than himself rather than abandon someone in danger 93 94 271. Asked why he helps Spirits, he says he cannot bear to see them suffer and is happy when they can smile 372.

Abilities & Skills

Spirit-power sealing

Shido can take a Spirit’s power into himself after gaining a sufficiently strong emotional connection, typically sealing it through a kiss 57 77 95.

• His first kiss with Yoshino produces no apparent transfer; a later kiss seals her power 77 95.
• Sealing leaves a connection through which power may return if the Spirit’s emotions become unstable 68.
• He seals both Yamai sisters, offering them a way to live separately rather than merge 278 282.

Borrowed Angels

Shido can manifest Angels belonging to Spirits whose powers he has sealed 271 272 276.

• Elemental Spirit: Lingmeng’s Angel lets him use elemental attacks, lightning-enhanced speed, spatial movement and mental illusions. He uses its time power to undo Yamai’s merger 271 272 273 419.
• Sandalphon: Tohka’s sword produces powerful slashes. Shido uses it to break the Yamai sisters’ wind barrier and to defeat two DEM Wizards without killing them 277 384.
• Limits: Angel use injures his human body. Elemental Spirit also strains his mind; space, time and mental abilities are especially costly. Limited use of Elemental Spirit alongside Sandalphon is safer than fully manifesting it, but does not make him a match for the strongest opponents 273 277 384.

Healing Flame

After sealing Kotori, Shido gains Efreet’s blue healing flames 192 272.

• The flames repair injuries suffered in combat or from using Angels, but healing itself is painful 272 384.
• The ability cannot help him while his Spirit power is frozen inside Yoshino’s barrier; Kotori also warns that it cannot save him from decapitation 89 94.

Disguise and negotiation

• Shiori: Shido uses a uniform, wig, makeup and voice changer to approach Miku, who reacts badly to men. Lingmeng helps maintain the cover story that Shiori is Shido’s cousin 300 302 304.
• Spirit outreach: He relies on patience and reassurance with Yoshino and offers to forgo sealing Miku if she will help rescue the captured Spirits 82 95 372.

Relationships

• Kotori Itsuka — His younger sister and Fraxinus commander. She directs his Spirit missions; Shido protects her when Origami targets Efreet 7 51 190 192.
• Lingmeng — A Spirit Shido seals and a frequent partner in rescues. She protects him, advises him on borrowed powers and calls him a hero despite regularly teasing him 57 94 384 372.
• Tohka Yatogami — A Spirit Shido vows to save. His concern for other girls can make her fear being displaced, but he repeatedly puts himself in danger for her 17 77 271.
• Yoshino — Shido promises to be her hero, retrieves her puppet and risks his life to reach her before sealing her power 82 85 93 95.
• Origami Tobiichi — A classmate who claims to be his lover. Their bond is strained by her determination to kill Efreet, whom Shido insists is not responsible for her parents’ deaths 103 190 192.
• Mana Takamiya — Claims to be Shido’s biological younger sister, though her missing memories and an old photograph leave questions about their past 110 113.
• Kaguya and Yuzuru Yamai — Appoint him judge of their rivalry. Shido rejects choosing which sister should live and instead offers to seal both their powers 217 277 278.
