From Nuka's perspective, the request proposed by Shava is acceptable. As far as Nuka is concerned, it's not a big deal, since Fei Gentleman's creation of the Seed of Distortion is fundamentally a way to further protect the Xinnai Land. Although this might mean its subordinate Minavaro might suffer a slight loss, it's actually inconsequential, as Minavaro's tentacles naturally fall off, and it doesn't touch the root cause, just perhaps a blow to face.
Therefore, Nuka doesn't mind it.
From Minavaro's perspective, Shava's sudden request is actually quite reasonable. Whether Shava is genuinely interested in the Seed of Distortion or just using it to reprimand Minavaro, this action guarantees the transgressions he committed at the banquet will be erased.
Just lose a bit to the annoying Fei Gentleman. If it allows him to gain Shava's forgiveness, it's worth it.
