Main CP: Insidious and cunning half-demon Naraku × exotic time travel girl Xiaoyu (Kawakami Kucha)
Hostess: "My name is Kawakami Kucha."
Yin Dao: "It's quite unique. How did you come up with your name?"
Hostess: "It may be embarrassing to say, but it is a homophonic meme popular among young people in our country. There, the pronunciation of "putting on underpants" is similar to that of Kawakami bitter tea. I thought it was abstract and funny, so I gave myself this name casually."
Yin Dao: "... You chose this name too casually!"
Naraku accidentally learned the origin of the heroine's nickname from Yin Dao's investigation of the heroine's background: ... What a strange person.
Although the heroine is not an outright bad person, her character is likely to be unlikable.
Purpose: Just to live again
