Here's a quick post about what's going on the yandere world lately.
A little over a month since the last Mayu doujinshi, we have already received another one.
Sakuma Mayu wa Unmei ga Mieru. This one is hentai free, and I quite like it. We'll probably see more of these in the future.
The entirety of
Hatuiki☆Syndrome has been translated and posted. The first chapter has the most yandere content in it, but I'd say it's worth it enough to read the entire thing.
One of the best yandere mangas to get consistent updates has been
Seeking for Death, and it usually had an update every month and a half. However, more updates have likely been put on hold. At the time of writing, the scanlator's
wordpress website has been deleted, and his user account on batoto now lists "Seeking for Death"
as a past project. If this is the case, hopefully someone else can carry on the series, as it has one of the better yandere characters in a while (I believe Eimi calls it a "Class 5 Yandere"). It's definitely worth the read, and I do hope we see more of it.
