Sailor Moon Frozen Stars: Chess Battle

Sailor Moon Frozen Stars: Chess Battle is an in-universe chess computer game based on the chess battle in Sailor Moon: Frozen Stars.

It made an appearance in the Sailor Moon Universe series, where Ami Mizuno's future descendant Amy Mizuno uses the program to learn how to play chess.

Overview
In the game, players can choose one from a total of 17 avatars, which consist of all ten Solar System Sailor Senshi, all four Ayakashi Sisters, both Frozen Sisters, and Tuxedo Mask. Each avatar has a move specialty when selected as the opponent in single-player mode; an example is Sailor Mars', Sailor Uranus' and Koan's being aggressive attackers while Sailor Neptune's and Sailor Saturn's are passive defenders. In the game, Sailor Mercury and Berthier's avatars are the "Grandmasters".

There is also a "Character Tournament Mode" where the Tuxedo Mask avatar isn't playable.

Trivia

 * The game is inspired by Battle Chess: Game of Kings and Chessmaster 9000.
