This episode opens with a monologue by Mai, saying that every meeting implies an eventual parting, but if you part, you may never rejoin. Still the heart remembers.
Then we move on the the beach where we repeat the same getting arrested gag that the first episode had.
The fun ends when Shirley arrives. She's the top tier Santa and she's taking over this territory. Mai will just have to leave.
Unless she can win a magical duel.
Mai summons things, and Shirley's magic makes them humongous, for some reason.
