Doubt, Arisa Recommendations
Even tho Doubt is a bit more horror-ish, both manga are about a game which includes death. Kinda different, yet similar.
Doubt is scarier than Arisa but the mystery is very similiar in both manga
Both stories have something to do with a cellphone that connects them to an unkown person(s). The stories also seem to be pretty guilty, in the beginning, but in the end it turns out te be really dark and kind of twisted. (Doubt is actually more of a horror story btw)
