Tanjirou and his comrades embark on a new mission within the Yoshiwara Entertainment District to face the demon Daki.

The first episode is a summary of SM, SM R and SM S, the second episode is about Haruka and Michiru on a cruise ship. They fight one of the SuperS enemies and decide to leave this villain to the classical Sailor Team. (That's an explanation why the outer Sailor Team doesn't appear in this season.) In episode 3 Chibiusa uncovers one of her classmates as a monster and fights her with the Sailor Team in a vampire castle.

"The Shepherd," an urban legend of Shiomi Academy, is said to appear before hardworking students to grant them a wish. While engrossed in a book inside the school's renowned Great Library, Kyoutarou Kakei, a second year student and the Library Club's de facto president, receives an email from the Shepherd foretelling an event that will change his fate. Worried by the message, Kyoutarou rushes over to a nearby train station and encounters fellow student Tsugumi Shirasaki, whom he saves from being hit by a derailing train. Grateful for his heroic actions, Tsugumi joins the Library Club and invites Kyoutarou to participate in her mysterious "Shiomi Happy Project." Together with other new members of the club, they strive to make the academy a better place and uncover the identity of the enigmatic Shepherd. [Written by MAL Rewrite]

Usagi and Chibiusa overhear two girls talking about the Sailor Senshi after they see a poster. Humorously, as the girls discuss which is the smartest, most elegant, strongest, and the leader of the Senshi, Usagi claims those titles for herself. Chibiusa shakes her head at Usagi's delusion. Clips are shown from the debut of each Sailor Senshi, and that girl's image song is played in the background. When even Tuxedo Mask is mentioned, and the girls go to leave without having mentioned Sailor Moon, Usagi butts in on their conversation and asks them directly about Sailor Moon. The girls give a series of glowing compliments about Sailor Moon, but unlike they did for the other Senshi, they also list her faults. After the girls leave, Usagi sarcastically apologises for being a clumsy cry-baby and then bursts into tears. (Source: Wikipedia)
