Aye vvv some warnings in stuff

Len has lately been having very many problems with his singing and "master" has brought to Len's attention that if he doesn't improve his singing he wont be able to be updated (due to more popular Vocaloids needing to be improved) or he may even get deleted and erased as a Vocaloid for good!!
This has made Len very sad and distressed making him loose confidence and not caring what happens to him. Kaito has noticed Len's strange behavior and finds out what may happen to Len. Now he has taken it upon himself to save Len!
Will Kaito be able to?? Read to find out （＾ω＾）
(this is my first fanfiction so it may be alittle all over the place. also excuse the long description (⌒-⌒; ) hehe)
