The Eroica series (3S and 3E) consists of works created as by-products of the author's gaming. To get a feel for the basic framework, you can try Eroica (the mobile game) with a guest account.
3S includes Sinfonie, Symphonia, and Sonata, and is based on the content already released in the game.
3E includes Eve, Ever, and Even, and is based on the game's setting and background.
Updates will come whenever inspiration strikes. (Writing is the author's habit, but publishing online isn't.)
The author isn't here to pull any stunts; I'll simply tell an ordinary story.
Also: I'll keep a copy on A Site.
