Arc 4: Eternal Contract

Arc 4, Eternal Contract, has been fully translated.

Credit for these translations belongs to the Summary Anon, whose only known identity is his email address,, as well as his Mega Archive. (This site is not affiliated with Summary Anon). As Arc 4 has 130 chapters, Summary Anon divided the Arc into phases, with each phase featuring a certain amount of chapters.

The anime adaptation left off at the end of Arc 3, without having adapted the interludes bridging Arc 3 and Arc 4; if you’ve just finished the anime, you’ll want to start with those, then proceed to Arc 4.

All credit for header art goes to HaruSabin.
