Jibaku-kun: Zero no Ki no Kajitsu (ジバクくん 零の樹の果実 ワールド) is a cancelled Action RPG that was in development by Enterbrain and Media Factory for Game Boy Color. The game is based on a manga / anime series by Ami Shibata and gameplay is kinda similar to the Tales Of series: players can explore the world and its cities, talking to NPCs and resolving quests, while fighting monsters in side-scrolling combat.
This is one of the playable GBC prototypes that was found in the Nintendo Gigaleak in September 2020, so luckily it was preserved: a few screenshots and gameplay footage are available online.
