Hello, i'm from Brazil and i have to say i loved this game (sorry rusty english)
So I play everything in Visual novel world, Japanese, otome eroge, Dating sim, Halloween Otome (i Love it too). And This game is awesome, story , characters and all this is amazing. I confess i get scared sometimes too. So i loved too all characters, Kaichi, Chain, Roya, Ikuya, Lioji.
I would play a game with all the secondary characters. Although it is an indie game the quality of it is incredible. Thank you so much for such a beautiful game and passionate characters.
