* In the flashback to 2020, Iwase says he has been working as an SP for four years. If this is not an error, it means that he was an SP starting in 2016 and then went back to the SP training school in 2017, where he was studying when Ishikawa and Nishiwaki came to the LADG as rookies. However, the evidence points to that number being a mistake.
