Second Season of the final arc of Gintama.

Akihiro is a teenaged boy with fantasies. He's about to have date with his girlfriend Miyuki when he finds a strange carpet on his way home. Home, a pretty and over-energetic girl named Malon appears from the carpet. She tells Akihiro about the world of Phantasia and wants to live with Akihiro. But even if Akihiro loves pretty girls, he becomes angry with Malon's magical powers and drives her away. The maniac wizard, Roll, who wants to kill Malon, doesn't help at all.

Some of the characters get together and talk about "regrets" they have after 4 years of anime Gintama. Soon they fight over who gets more screen time. Special animation shown at the Gintama Haru Matsuri 2010 live event.

Collaboration anime between Gintama and Monster Strike.
