Hotaru has upgraded the old Mikan robot she showed in the past, now it is called Amanatsu and she behaves and reacts exactly like Mikan in almost every way. Afterwards Hotaru is being praised by a CEO of a company about her new invention when another student in the same department challenges her. This student will do anything to win and with all the "help" Mikan and Amanatsu are trying to give Hotaru will she be able to beat him.

I really liked this episode, and all of the Amanatsu stuff was great (much better than I expected).
