Ayato Aishi (Yandere-kun)

He asked his mother if he could go with them and study online for a few weeks before returning home to attend  Akademi High in person. Reluctantly his parents agreed with the possibility that his Senpai may be in America, but they never made it as the plane they were on had an engine frailer and crashed. There were no servicers and as the Aishi family used fake passports no news of the family was herd and he is still enrolled to Akademi.
