Gakuen Alice 40

Mikan gets separated and natsume and company are trapped in a dungeon. So there is this evilguy with glasses. Mikan's mom and her light haired friend takes orders from this guy. So this evil guy orders Mikan's mom to steal Mikan's alice or maybe she volunteered.

On her way to the cage that Mikan is in she recalls some stuff about her past when she was in school I guess. She remembers this guy, and then we see her crying in the rain and the same guy comes again, and then we see her running with Mikan in her arms.

She reaches the cell and Mikan immediately recognizes that she was the one that she met when she was with Hotaru and when Hotaru got hurt. Mikan yells at her mom telling her that Hotaru is hurt because of her and her company. Mikan's mom realizes that there is camera in the room and slaps Mikan away. Then she pretends to steal her alice, and when doing so leaves a small bottle with the name ZERO on it. Thats where they get the Z-group from. The bottle can do give people their alice back.After Mikan's mom leaves, Mikan escapes from the cage and meets up with Natsume and co.
