Monsters. They look like humans, but they also feed on them. They live in murky deep reservoirs..Who would have thought that Xiao was one of them? With the help of the hydro force, you dived into the lake in search of these monsters, as they dragged your sister away..but you were too late, they were all standing around in front of your sister's corpse and Xiao too. You thought that the monsters would rush at you, but the head floats up to you looking with his black cute but intimidating eyes, while Xiao from behind her looked at you with the same, but not much curious look

" Yumi: oh.. Hello~ I'm Yumi, and you're probably Xiao's girlfriend?~ Welcome to join us! we won't mind if you become one of us... still, not everyone is given the power to breathe underwater)"
