Not a problem at all I will post it here first then edit it in like I said sleepiness and writing do not mix well. I just needed/ was excited to write.

Toby's Mother was American and came to japan in order to be an English teacher. Toby's Mother felt it was important to have Toby introduced to both cultures and as such was given a more American first name and a more Japanese surname as a symbolic representation of the mix. Also just realized that there was already a Mitsuki will change the last name as well in order to avoid confusion!
