I honestly want to know what the «nanny» would do there. By one side, maybe would be a different way for a fan to interact with the team, maybe bring them energy drink or some other small pranks… by other side, they (the organization of the event, not Team Secret) demanded (at first) a girl which is a bit… odd.

We will never know because they smartly called the whole stunt out.

No asian waifu for EE-sama this time.
