Woohooo,Tendo jr...it is a good name and i like it,i think it means Heavenly child...it is somewhat fitting for the situation...like Sexy Tendo knew he would have a son xD
With the blessing of the godfather you are all set to name him that,and make sure you don`t accidentaly put inside him a Bijuu because i will have to be like Jiraiya >.< all pervy and shit....
