Little fun fact, this group was nicknamed the anti-emo force four by my friends, thus they claim Chikaru, (The black haired one) is like me.
A little about Chikaru: She enjoys various activities, and loves clubs. She's an eccentric person, and has many strange hobbies, but always has a smile on her face. Very little can affect the care free Chikaru, even in times of great depression, she can keep her head up.
That remains so true, as the entire series she never once complains, cries, or even panics.
