Everyone wants to send presents to mikan since she can't come to the Xmas party. Natsume is sending her the repunzel book, to hint that he'll save her. But they don't want ESP to get suspicious, so everyone else is sending other Grimm books.
ESP found out that Shiki worked with yuka and the Z terrorists and stole the Alice stones of his clones. He demands that Shiki return them or his deal will be off... He discusses this with noda, jinno, and HSP and thinks that using mikan to get the Alice stones out of him would put mikan in danger.
The Xmas party scene is really cute. Shiki gave mikan a live feed of the party so she wouldn't feel lonely. The others say this would just make her feel worse. Mikan is depressed from watching it, and bear gives her a present. Then shiki teleports everyone's presents to her.
