Little Tail Story (Japanese: リトルテイルストーリー, Hepburn: Ritoru Teiru Sutōrī) was a free-to-play online social role-playing game developed by CyberConnect2 and published by Bandai Namco for Android and iOS.

[2] Little Tail Story is a 3D role-playing game presented from an overhead view where players undergo quests that involve exploring areas and battling monsters to obtain treasure.

[3] The original classes include Swordsman (剣士, Kenshi), who deal heavy damage to a single opponent; Knight (騎士, Kishi), who use lances to hit in a straight line; Guardian (衛士, Eji), who carry shields and attack in a horizontal line; Warrior (闘士, Toshi), who use hammers to attack a circular area; and Witch (魔法使い, Mahōtsukai) who can hit all enemies for light damage.

[10] Music for the game was handled by composer Chikayo Fukuda and vocalist Tomoyo Mitani, collectively known as "LieN", who previously collaborated on the soundtrack for Solatorobo: Red the Hunter.

The title's official theme song is Hikari no Mukō e (光の向こうへ, To The Other Side of Light), which was performed live one month before the game's release during LieN's "Voyage" concert event in Japan.
