Lion and her friends are enjoying a tea party in Yuko's room when they unexpectedly learn the date of her birthday. What's more, it's today! Yayoi proposes throwing a surprise party for Yuko, and Lion suggests having a pajama party.

Class S faces their first practical exam. Yayoi is aiming for first place, and gets even more enthusiastic when she hears the examiners will be active dute Logicalists.

It's class S's first practical exam. Yayoi intends to take first place, and when she hears Logicalists currently on active duty are going to participate in the practical exam, she puts even more effort into her goal.

With the exams over, Lion approaches her first ever summer break. Lion's friends come to her home to enjoy their vacation. What kind of fun memories will Lion create with her first trip with her friends?

It's the second half of summer break and Yuko is spending her days at Shirakaba Dormitory as usual, but she's also worried about what her plans for the future should be. Her friends on the student council try to give her a pep talk.

The long summer break is over and the second semester starts. Pirari Academy is having its first ever school festival, and Lion and her friends think about what kind of event they should do.

Pirari Festival is nearly here, and the script for the play Lion and everyone in Class S is going to perform is complete. Everyone's busy preparing and rehearsing, but Lion just can't seem to get better at her role regardless of how much she practices.

Winter has arrived, and the practical exam at the end of the semester will be a tournament. Lion's first match will be against Nina, who is becoming flustered trying to figure out how she can prove herself to ALCA.

With the exams over, Pirari Academy enters the winter break. Everyone at the dorm heads home for New Year's Eve, leaving Nina alone to fully enjoy some peace and quiet.

ALCA has finally finished deliberating over the incident that happened at the end of December. Fortunately, they have decided that no one will be punished for what happened, and actually consider Nina's actions at the time to be worthy of praise.

Lion, a princess from a small country, has enrolled in Pirari Academy in Hokkaido. She was looking forward to starting her fun new school life with Nina, the girl she admires most, but something is amiss.

After just one night at the academy, Lion finds tests waiting for her in the morning, and is disheartened after some very disappointing grades. She cheers up after talking with Yuko and the student council while eating Yuko's home made cookies.
