Coffee and Donuts is Tiki's second side story in Tokyo Mirage Sessions ♯FE.
Story[]
At the Bloom Palace, Tiki requests that Itsuki go to the Hee Ho Mart and bring her a highly-popular type of donut that Tsubasa told her about, as she wants to try something from their world. However, when Itsuki get there, he discovers that they are sold out, with the last bag being bought by a high school girl.
As it turns out, the girl in question is Tiki=Waifu, who bought the donuts to have something to eat while she made her music. Fortunately, she allows Itsuki to have one as thanks for helping her escape from Illusory 106. When he returns to Tiki, however, she reveals she can't actually eat the donut due to being a Mirage, so she has him eat it instead and describe the taste to her. After doing so, Tiki reveals her love for their world due to its many customs, and that she hopes to keep it safe by helping Itsuki and his friends.
Completing this side story unlocks Tiki's Backup Skill Performa_Finder.exe, which gives a chance of obtaining two Performa from a Session Attack.
