Satou trains with Marse, hoping to beat Granart in the sword duel to court her. Satou is torn between facing her fairly to look cool for Hime, and prioritizing his duty as the Ring King. However, the Abyss King's evil clutches are approaching Needakitta.
So scrubbing is what they meant 
by "surrendered her body"...

Так значит, под фразой «доверила тело»
подразумевался пилинг.
