 * plotrole====Jinmengyo's Character Quest===

The story opens with Jinmengyo approaching {{sbpg|Serval|Nexon Game}} and the protagonist in Japari Park's Park Central, excitedly informing them that today is the Japari Festival, and asks the two of them to go with her. Serval notes that the festival was newly created, and confirms with Jinmengyo if the event will have stalls and events. Jinmengyo tells Serval that she is correct, and expresses her enthusiasm for festivals, telling her about how she can also dance at the event. Serval decides to go, and says she will ask {{sbpg|Snow Sheep|Nexon Game}} to do her hair in a manner that will fit the festival, and Jinmengyo decides she also wants to have her hair done to match the festival's yukata. Snow Sheep promises to put all of her skill into giving the two a fitting hairdo, and Jinmengyo thanks her. Stating that a girl's hair is her life, Snow Sheep prepares to tend to the two's hair.

While waiting and getting their hair done, Serval asks why Jinmengyo likes festivals so much. She mentions that of course, she also likes festivals, but notes that Jinmengyo seems exceedingly lively. Jinmengyo responds by telling Serval that she enjoys rare things and being surprised, and that festivals have many interesting things. She also mentions that festivals are very busy places that everyone seems to look happy at. Serval thinks the same, and says that festivals are special days. Jinmengyo gets restless, saying she wants to go to the venue soon, and Snow Sheep asks her to be still or the hairdo will become untidy. Serval notices that Ceruleans are approaching, and Snow Sheep asks the two to wait while she finishes up, but Serval becomes nervous and asks her to be quicker. Jinmengyo, seeing Serval in danger, then decides to take care of the Ceruleans herself.

Later, after having escaped the danger, Serval thanks Jinmengyo for saving her earlier, and the group arrives at the Japari Festival. Jinmengyo becomes excited upon seeing the colorful stalls. {{sbpg|Masked Palm Civet|Nexon Game}} goes over food choices at a nearby stall - apple candies, apricot candies, and chocolate bananas, and is overwhelmed by how many good looking fruits there are. However, she has to stop to scold {{sbpg|Atlantic Puffin|Nexon Game}} for eating other people's portions, but Puffin simply asks Civet to share her snack with her. Serval visits the stall, seeing yakisoba and cotton candy, and has difficulty picking what to eat. Jinmengyo jokes that Serval is a glutton, causing Serval to rebuke her statement. Jinmengyo reminds Serval that she also enjoys stall food, and that it's okay to eat a lot of food at such events. However, Civet suddenly cries out, as Ceruleans have appeared and are eating stall foods, though she seems more upset that she was told not to eat in excess herself. Serval ponders if the Ceruleans are imitating them, but realies that the stalls will be completely out of food if this continues, and rallies the group to fight the Ceruleans.

After the battle, the group approaches a dancing stage, and Jinmengyo marvels at the colorful outfits of the dancers. Seeing {{sbpg|Indian Elephant|Nexon Game}} on-stage, Jinmengyo notes that her dance is more extravagant and showy than it usually is. {{sbpg|Greater Bird-Of-Paradise|Nexon Game}} sees this as well, and states she will not lose in the contest of passion for dancing, and declares that she will perform a passionate samba. Jinmengyo calls Bird of Paradise gorgeous, and decides to dance on-stage with the two. However, in her excitement, Jinmengyo does not notice an approaching Cerulean, and Serval warns her, preparing to fight, exclaiming that everyone on stage is in danger.

Following the fight, Jinmengyo sees that a singing contest is about to begin, but Serval sees a familiar face, and becomes terrified. At that moment, {{sbpg|Crested Ibis|Nexon Game}} begins to sing. {{sbpg|Scarlet Ibis|Nexon Game}} hears, and smugly states that she is more suitable to become the Japari Festival diva, and begins singing herself. Serval, in pain, wonders how it has come to this. In order to protect the peace of the festival, Jinmengyo decides to join in on the singing contest. Serval warns that if she becomes too close to the singing, she may be in danger, but she is too late, and as Jinmengyo approaches the two birds, she suddenly faints.

After fainting, Serval laments her inability to warn her, but then realizes that Ceruleans have snuck up on them. She cries out to Jinmengyo, telling her to run, but she is still dazed and unable to flee. However, upon seeing Jinmengyo's mask, the Cerulean becomes scared and leaves. Jinmengyo then recovers and is surprised, and Serval is amazed at how Jinmengyo's mask repelled the Cerulean. She comments that it must be because the mask looks like the face of a demon. Jinmengyo chuckles, and says that because of this, any who may disturb the festival have left. The two Ibises praise her, and Serval realizes that the two have also stopped singing after seeing Jinmengyo's mask, and she declares that she is saved. Jinmengyo and Serval then enjoy the rest of the festival with everyone. Barn Owl is the one who makes her masks and considers it as her masterpiece
