The episode begins with Cid's classmates finding VIP tickets for Mitsugoshi Hot Springs Land in his room. They believe these tickets are their big chance to impress women and decide to use them to invite girls to the hot springs. Among them are members of Shadow Garden, who interpret this as an encrypted message from Shadow (Cid) and decide to join them, believing it to be part of a larger mission.

Mitsugoshi Hot Springs Land is a newly opened resort centered around the legend of the Dragon's Tears. The resort is a creation of Shadow Garden and was built at a location where Cid (Shadow) once showed interest in the local legend.

The classmates arrive at the hot springs along with the members of Shadow Garden. The boys, armed with questionable dating tips from a book, try to impress the girls. Meanwhile, the members of Shadow Garden search for clues about Cid and the supposed mission.

Throughout the day, the members of Shadow Garden ponder the legend of the Dragon's Tears, a story about a princess and a dragon, which they believe might be connected to their current situation.

During their stay at the hot springs, an anomalous magical signature is detected underground. It turns out that the hot springs possess magical properties that could make them a lucrative business for Shadow Garden. The members speculate that this was Shadow's (Cid's) intention all along.

The episode ends with the classmates, who can no longer remember the events of the day, reflecting on their experiences.

In conclusion, it's a filler episode with lots of fan service :)
