Takumi-kun Series: That, Sunny Blue Sky

A 2nd year student is assigned a handsome new roommate at the start of the school year.

Takumi and Gii are now a couple, but Takumi is still uncomfortable with showing affection. Not only that, but Takumi grows jealous when Gii starts paying attention to a good-looking first year student. Is Gii's love really that fickle?

Another school year is starting. Upon meeting up with Gii, Takumi is worried when it turns out Gii has changed, suddenly acting cold and distant. Could their relationship be in danger for real this time?

Unlike the three previous films, Pure focuses on the relationship between Misu Arata and Shingyouji Kanemitsu , which begins when Shingyouji takes the test to enter Shidou Gakuen . That's when he meets Misu and falls for him. Then we come back to the present where the sempai who admires Misu appears, bringing Shingyouji problems and jealousy.

Takumi's feelings for Gii grow even stronger when they become roommates — but their close bond raises the ire of a jealous classmate.
