Kemono Friends (2015 Mobile Game)
The player finds themselves in Japari Park with no previous memories. There, they meet Mirai, depicted as a rookie Park Guide, as well as Serval. The player learns that Japari Park is a massive, open zoo where visitors can play with animal girls known as Friends, but that the park is currently closed due to an outbreak of Ceruleans. It is during this prologue that the party first encounters the strange, Serval-like Cerulean named Cerval.
The party meets Caracal, who claims that Serval stole her Japari Buns. However, Serval has been unwittingly framed by Cerval, the true culprit. They accost and do battle with her, after which she mumbles something about "going back to the Queen". Fearing that Cerval will cause more mischief that Serval will be blamed for, the party follows the Cerulean to the next region. Additionally, Caracal joins the party.
Pursuing Cerval, the party seeks help from the "Wiseman". On the way, they meet Crested Ibis, a troubled singer. The ibis explains that her she's troubled not only that her singing is terrible, but also that it apparently attracts Ceruleans. The party suggests that the Wiseman may be able to help her too, so she tags along.
Once they finally meet this "Wiseman", it turns out to be a pair of owls, specifically Professor Konoha-chan and Assistant Mimi-chan. They give Crested Ibis medicine to improve her voice, but it doesn't work at all, attracting even more Ceruleans than before. The discouraged bird Friend is about to give up singing for good, but the party encourages her to keep with it. She then gains the ability to heal in combat using her voice (although she still sounds terrible). It turns out that Ceruleans were attracted to her voice because her singing was so bad that even they couldn't bear it and tried to stop her by force. But with its newfound healing ability, the effect is mitigated, lending to a (relatively) happy ending for the chapter. Afterwards, Professor Konoha-chan informs the party that she saw Cerval heading to the desert area.
The party arrives in the Sankai Region and finds that all of its oases have dried up. Not missing a beat, the heroes set out to find out what's going on. There, they meet Arabian Oryx, who is looking for her missing friend Lulu, a Thomson's gazelle Friend. As it turns out, Lulu set off on her own accord to prove herself useful to Arabian Oryx by solving the problem of the desert's empty oases herself. She and the party locate a large Cerulean that drank all of the water in the desert. They defeat it, and Lulu joins the player's party permanently. Unfortunately, Cerval gets away in the process and the group follows her into another region.
