Presents himself as a sharp, helpful assistant on the investigation. In reality he is Kira, and struggles greatly—his usual tricks, charm and logical loopholes never work on the kids, who call out every inconsistency they notice straight away.

The world’s top detective. He breaks all standard procedure when the case stalls, scouting and bringing in the seven kids because he sees adults’ biases and assumptions as their biggest flaw. He listens to their questions fully and backs their right to challenge anyone.

18, quiet and sharp, Wammy’s most gifted successor. He initially doubts the kids’ place but quickly respects their clear, uncluttered thinking—he works alongside them, trading puzzles and observations, no ego in the way.

18, laid-back, tech-savvy Wammy’s graduate. He teases the kids at first but quickly bonds with them—supplies games and gadgets, and loves how they spot patterns he overlooks while digging through data.

18, sharp-tongued, driven by outdoing everyone else. He mocks the idea of child consultants at first, but quickly stops—they see straight through his bluster, and he’s forced to admit they catch details he misses.

Famous model, loyal and fiercely devoted to Light. She thinks the kids are adorable, brings them treats and toys, and doesn’t grasp the full weight of their role—though she often accidentally gives them small, useful clues without realising it.

Sharp, poised news anchor and Kira’s public voice. She sees herself as Light’s chosen partner, tries to charm and impress the kids, but is flustered when they dismiss her polished speeches and press her on things she can’t explain.

A rigid, devoted prosecutor who sees Kira as absolute justice and Light as infallible. He values strict order and moral clarity, and is genuinely interested in raising children to do what is right—so he treats the seven with unusual seriousness, but freezes completely when they question whether his rules are actually fair.

Earnest, anxious team member. Worried for their safety at first, then becomes their biggest supporter and treats them as equals.

Watari – L’s calm, loyal assistant and Wammy’s founder. He handles the kids’ needs, keeps things running smoothly, and quietly backs L’s choice.
