I apologize, but there is no discomfort in addressing you in such a way.
[Except Souji's fidgeting because when was the last time he'd ever used such formal language?]
Ucchii-- ... Utsusemimaru-san... is a very precious friend to all of us. I want to thank you for everything you have done for him and for the opportunity to fight alongside him.
[Souji bites at his lip before continuing.]
He has missed you greatly. Please be gentle with him.
