Mayu just keeps getting geekier and geekier:
Last year I saw Watarirouka Hashiritai's Mayuyu & Rabutan at Animate.
I was at the 6th floor in the figurine section, and there they were in front of me. Rabutan then left and only Mayuyu was left. After that, for about 2 hours, I was looking at figures. And during that time, Mayuyu too, was looking at figures. Even when I was leaving, she was looking at a figure of Sebastian Michaelis from Black Butler. Mayuyu could be an anime otaku, I think.
Mayu's officially the geekist idol ever! So, Acchan's in love with Robaato Pattinson while Mayu's into... anime characters. Since it's impossible for her to get Friday'd I bet she's gonna get caught buying hentai/yaoi one day
