Aika lost both of her parents at a very young age and inherited a huge wealth. Problem is that she wouldn't be able to withdraw any of it until she's 18. Aika's parents also granted her a scholarship Aika was then sent to live at an orphanage. The orphanage was old and low on funds though everyone there was extremely generous. Oh did I forget to mention that Aika is extremely tech savvy, a gamer and a child prodigy. But she was also extremely lazy and hated doing work so she always just barely passed all her classes. She went to Ouran because she thought that she may as well since she has a scholarship fund from her parents. There she meets Haruhi who she befriends immediately. They both were looking for a quiet place to stay -well game for Aika- and who knows what awaits them.
I don't own Ouran High School Host Club. I only own my OC.
