Sooo I just figured out chika fujiwara best waifu there is Chika is a cute fair-skinned young girl with shoulder-length silver hair (light pink in the anime) that has a black bow in the middle of her square bangs, blue eyes and she has a larger chest size despite being shorter than Kaguya Shinomiya.

She is usually dressed in a Shuchi'in Academy high school uniform.

Chika is a bubbly eccentric girl who almost always has a smile on her face. Always looking to have fun with her fellow student council members, she is often the one to come up with strange activities and ideas that entertain herself and the others. She is mostly oblivious to the atmosphere of the room, resulting in her being an unpredictable element that ruins many of Kaguya Shinomiya's and Miyuki Shirogane's schemes to make the other confess, and Ai Hayasaka as Chika is a threat to her tasks.
