制作物
Free, open tools and experiments — things I build and give away, because they should exist and shouldn't cost anything.
Less decoding. More reading. Find your rhythm with kana, N5 kanji and vocabulary — scored sprints, lesson filters, a quiet Flow mode, and another shot at your missed words.

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.
