The Tower of Mysterion ch. 1-12

I started this manga because the title was interesting "The Tower of Mysterion" so my hopes for this one are really high.
I started reading the first chapter and everything was normal... a girl and her two male firends. So at first I thought that maybe there won't be much mystery here and only romance... when the second girl appears and starts a date with one of the two boys, I was a little disappointed but at the end of the chapter my hype was at his peak because a mysterious death (of the second girl) happened! This escalated pretty quickly into a horor story with a great mystery to solve.
I quickly finished all the 12 chapters available and wanted to know more since they started to explain a little (really little) of what's happening!
The drawing style is cute and this helps for the romantic scenes and to don't let the story be too much dark (because there's alot of deaths) and depressing.

My rating: 8/10
