Tonkatsu Box is a collection manager for games, movies, TV shows, anime, visual novels, manga, books, music, and podcasts that tracks progress, ratings, and shelves for all of them in one place. One search field queries fifteen catalogues, from IGDB, TMDB, and TVmaze to AniList, MangaDex, OpenLibrary, ComicVine, and Podcast Index, and a result can land in several collections at once. Collections organize by platform, genre, or anything else, with grid, list, table, and board views, drag and drop ordering, global tags, and bulk actions across a selection. Progress speaks each medium's grammar: episodes for series, pages for books, chapters for manga, listened track checklists for albums, plus statuses, ratings, dates, and replays. The episode tracker unfolds seasons with posters, stills, air dates, and synopses, and marks one episode, a whole season, or the next unwatched one in a tap. Statistics turn the library into numbers with per type breakdowns, a month by month ribbon, platforms, formats, tags, best against worst, and a shareable summary card. Visual boards arrange posters, notes, and connections on a free canvas, and tier lists and mood grids rank and lay out items for export as PNG. Importers read Steam, Trakt, Simkl, MyAnimeList, AniList, Hardcover, and RetroAchievements libraries, plus JSON and CSV, and collections travel as offline .xcollx packages.
