With issues of the latest issue of Tech Gian and Type-Moon Ace "leaked", news of Type-Moon's upcoming projects are practically everywhere now:
Mahou Tsukai no Yoru - Not much news here, the game was announced by Type-Moon a couple of weeks ago. The story is based on one of Nasu's (TM co-founder) early unreleased novels. The story centers around the life of magician Aoko Aozaki and her sorcery teacher Alice Kuonji, who live together in a mansion. One day, a young boy called Souichirou Shizuki joins them, and things become interesting...
The "bad news" is the game will be "All Age", meaning there are no ero contents, of course, being a TM game, the story is what really matters. Another thing to note is that the art will be done by Hirokazu Koyama, making this one of the first TM game not drawn by Takeuchi.
