Reversa

Reversa (ヒョウヘンヌ Hyōhennu) is a Heartful-tribe Rank A Yo-kai and, when combined, the fusion of Happierre and Dismarelda. According to the Yokai Encyclopedia, it says  "One moment she's happy, and the next, she's sad. She can be more difficult to deal with than Dismarelda sometimes'.

How to befriend
Reversa can be obtained by fusing a Happierre and a Dismarelda together.

Alternatively, wild Reversa can be found at Liar Mountain in the Yo-kai World.
