After he and his brother were "Adopted" by Blaid as aprentices, he became Blaid's loyal servant and vassal, willing to do anything to get appreciation for his actions from his new Master. More than once, Shinji disobeyed commands to go on his own made up missions and when it came to punishment, Blaid dismissed it as Shinji actually trying to impress his Master. The only time, Blaid got angry and ranted at Shinji for disobeying orders, was when Blaid's son Yami came under attack by Shinji when Shinji saw Yami as inferior.
