Riolu in Equestria 66

Riolu gets to school. He is asked to come to the principal’s office. Principal Celestia tells Riolu that his homeroom teacher is going to visit Rarity’s house to see how he’s living. Principal Celestia was hearing rumors that he and Rarity are cohabitating each other. Riolu’s eyes are wide open, a sweat drop appears, yells in shocked, “cohabitating!” Principal Celestia says calmly, “Calm down, I said it’s just a rumor. Just prove to your homeroom teacher that you and Rarity are just living together and you’re just renting the place.”

Back at Equestria, all of the royal families and all of the royal guards disappeared. A royal servant said that when she came into the throne room, she found no one, but toys everywhere. A royal servant also said that she saw a filly in the throne room. She picked up the toys and left the palace.

Back at the human world, Riolu’s homeroom teacher enters Rarity’s home.

Riolu shows his homeroom teacher that he and Rarity are not cohabitating together.

A homeroom teacher found a red panty brief on Riolu’s bed. Riolu gets nervous and he immediately clams that the underwear belongs to Rarity and it must have got mixed up in the laundry.

The homeroom teacher believes him. Riolu is able to continue going to school and to stay at the house.

The homeroom teacher left the house. Riolu sighs in relief. Rarity looks at the red panty briefs and she calms that the underwear doesn’t belong to her.

Riolu remembers that the red panty briefs belong to Zorua.

(Flashback)
Riolu and Zorua were sleeping together, but it wasn’t serious.

Riolu felt reckless. He got a phone call. It was Kino. She has a mission for him. He must go undercover.

Back at Equestria, Wanju is dragging a toy box to a flying castle fortress. Inside the toy box are the toys. The toys are all of the royal families and all of the royal guards.
