Shida Manaka, or "Mona," was a moodmaker in Keyakizaka46; she got along with everyone and would make episodes of "Keyakitte, Kakenai?" feel like backstage chatter for her fellow members. Her laugh is iconic, as it was commonplace and probably the loudest in the room every episode. She was very active and had appearances both with the group and by herself. Despite that, she would cut short her status as a member in late 2018, after taking a year long break. She would resurface into the public eye in April 2019, and since then has been tackling various facets of work. Nowadays you could see her filling in as a Niigata local radio regular and managing her own skincare brand, aptly named "pui."
