Description
Shinji Inukai is one of five guardians protecting Tamayori Princess Tamaki Kasuga. A 15-year-old member of the Shugogo lineage, he stands 165 cm tall with purple hair. Documented eye colors vary between amber, green, and brown, and his blood type is AB.

Born without supernatural abilities in Kifumura village, Shinji was abandoned by his birth family. The Inukai household adopted him but subsequently discarded him due to his perceived powerlessness. During exile, he forged a contract with the wolf spirit Logos and the organization Logos, receiving the codename "Fünf." This pact granted him shelter and respite in exchange for pledging aid to a future holy woman and supplying Logos with intelligence on the guardians and their artifacts.

Shinji presents as reserved, polite, and gentle, often employing honorifics. He demonstrates fierce loyalty to his fellow guardians yet exhibits tenacity and stubbornness in pursuing objectives. His hobbies include cooking, with noted expertise in dishes like stuffed cabbage and rice omelets. Initially introverted and socially hesitant, he gradually opens up to Tamaki and the guardians.

His supernatural abilities manifested later than others. After leaving the village for training, he developed Kotodama—the power to manipulate objects and people through speech. This enables immobilizing targets and enhancing allies' physical attributes. Following Tamaki's awakening, he gained shield creation and accelerated healing. He primarily provides tactical support in combat.

Bound by his Logos contract, Shinji betrayed the guardians by leaking information, motivated by a desire to eliminate the Onikirimaru threat and secure peace. Exposed, he was forgiven by most guardians, though Mahiro Atori reacted violently. A significant revelation identified Mitsuru Kotokura as his twin sister; separated in childhood and unaware of their kinship, they developed romantic feelings before discovering their relation, creating emotional conflict.

Shinji's journey involves reconciling loyalty to the guardians with his obligations to Logos, navigating the complex familial bond with Mitsuru, and embracing his guardian role despite his past betrayal.
