制作物
Free, open tools and experiments — things I build and give away, because they should exist and shouldn't cost anything.
Free, structured Japanese learning tools — Kana Speed Reader, N5 study guide, particle drill, sentence scramble, and pattern drill. No login, no cost. N4 → N1 in progress.
Open Hub 改 App · Free · LiveA life RPG that gamifies self-improvement. Track six stats — Intelligence, Language, Craft, Vitality, Charisma, Discipline — earn XP, climb ranks from E to S★, and build daily streaks. Inspired by Solo Leveling.
A free online university drawn as a little anime campus you explore door by door — the sky follows your clock. Japanese (N5→N1), an IGCSE hall with eight subject rooms, and a sealed A Level tower. Flashcards, PDFs, and recorded lectures, all free forever.
Step Through the Gate制作哲学 — Build Philosophy
Every project here starts as something I wished existed and ends as something anyone can use for free. No paywalls, no accounts, no tracking. I build in the open because knowledge is more useful when it isn't owned.
