Best Oshi no Ko characters

Hoshino Ai wins 69% of her duels and tops the Oshi no Ko main character ranking ahead of Hoshino Ruby, while MEM-cho sits at the bottom after 1852 duels.

The ranking reveals a commanding performance by Hoshino Ai, who distances herself from her daughter Hoshino Ruby by 121 ELO points. Ruby herself edges ahead of Hoshino Aquamarine by just 26 points, while Arima Kana trails by only 5 points at rank 4 with 1183 ELO. The tightest race unfolds in the middle: Arima Kana and Kurokawa Akane are separated by a mere 24 points, suggesting these two characters divide the fanbase almost evenly. At the bottom, MEM-cho registers 1120 ELO with a 44% win rate over 350 duels, indicating that while she commands a dedicated following, she struggles to outpace the core Hoshino family and their immediate circle in direct matchups.

This ranking draws from 1852 duels completed by 180 players across 6 contenders, updated on 10 October 2026. The volume of votes confirms sustained interest in the series and its cast, with each character facing hundreds of head-to-head comparisons. The data captures the community's clear preference for Ai as the standout figure, while the compressed middle ranks reflect genuine uncertainty about secondary favorites.

How this ranking is computed

Every duel won lifts a contender and every loss drops them, by an amount that depends on the opponent's strength: beating the leader is worth more than beating the last. It is an ELO, the same principle as in chess. Duels are not drawn at random — an adaptive entropy sort puts the least predictable match-ups first, which settles the ranking far faster than a full round robin. A worldwide ranking is only published past 30 completed plays. Known limit: a contender who has faced few opponents keeps an approximate score, and the bottom of the table moves more than the podium.
