Takamina's Graduation Announcement from Mechaike Dokkiri SP

I'm still kinda shocked Takamina recently announced her graduation, especially so soon after the Mechaike dokkiri episode aired. This clip shows her fake graduation announcement as part of the dokkiri, but I'm wondering now how much of it was acting. Enjoy. ^_^
