Days of the Divine by Circle Pegasi
Biku is the shrine maiden for an angry god who's covered the village in mist. The mist takes away the memories of the people and a lot of people have already fallen victims to it.
I know there's tons of in-depth otome blogs out there. Please indulge me with my attempt of a short review. This is a free otome on Android and Ios. Yes, a full version not just some teasers to let you buy the game. There's also a Windows, Mac and Linux versions which you can download from the official website. This is the first time that I finished all the character routes. The only otome that I've I finished is Yo Jin Bo but I only played just one character ending. It's interesting to see all the side of the stories from different point of views and you will see the larger picture once you have seen all the endings. My first try ended with a bad ending right away. I tried to get Senrei first, then Maru and last, Liufan. I was bent on getting Senrei first, but among the three I enjoyed Maru's route. The other two was serious. For something that's free, it's good. Decent storyline, beautiful art and right choice of scoring.
