For my two cents, I think he might be participating in the Atura himself, but maybe just to assess the competitors. And in some ways demonstrate his own provess to others and especially Shuraka. Ofc he wont be his own knight, those titties need extra protection.
I feel like he's not one to go out of his way to do that and would just accept what the system gives him. And I don't see why he still needs to prove his prowess when he already helped protect Shu back then + Shu already knows his feats as margrave
