“	All that matters is this. I DO have a part to play in this world. I'm the brilliant detective, and I'm here to solve the mystery of Kaeru's death.	”
—Sakaido, FILE: 01 Jigsawed

Brilliant Detective Sakaido is the persona adopted by Akihito Narihisago whenever he enters id wells and the main protagonist of ID:INVADED. The original and most prolific "brilliant detective", he traverses the id wells of serial killers to try to uncover the truth behind the murder of Kaeru, and indirectly determine the identity of the id well's owner for Kura.

Appearance

Sakaido's appearance is extremely reminiscent of his counterpart Akihito, essentially being a younger version of him, appearing as a young man with green eyes and light pink hair spiked upwards. His clothing consists of a long brown trench coat, a lighter shirt, and a black vest, as well as large, flared black shorts, black leggings, and trainers. Most noticeably, he has a long yellow scarf.

While in Tamostu Fukuda's id well, his left arm is disassembled, losing his wrist, part of his forearm and his elbow.

Personality

The quirks of the Mizuhanome System mean that Sakaido remembers nothing of his life as Akihito every time he enters a new Id Well, essentially leaving him a blank slate each time he wakes up, meaning his personality is more innocent than Narihisago's, lacking the latter's trauma.

Though not immune to panic, Sakaido does show a calm, proactive mindset, quick to calm down and take proper action, shown when he discovered he could move his detached limbs and calmly put himself back together. He also was unfazed by seeing a young girl's corpse and the broken, distorted people of Fukuda's well, showing that he possesses impressive nerves.

Sakaido is also characterised by his extreme deductive mindset, being highly analytical and methodical in his work, perfectly willing to spend time focused on one particular clue, only moving on once satisfied, prioritising the case over his own survival. However, despite this drive, Sakaido is extremely empathetic, often taking into account the people in the case as people rather than just clues, occasionally derailing his investigation entirely to save someone in immediate danger. While in Nahosi Inami's id well, he cries over Kaeru's body, realising her death had no point and despairing that he couldn't save her.
