Imu's Seals are pretty interesting.
Will be interesting to see just how powerful the Deep Sea Seal is for one and how it compares to Domi Reversi boost wise as that seems to be forced seal of sorts with similar perks except with side effects and of course a lifespan cost.
Domi Reversi kinda gives off Ascended Super Saiyan vibes with the size increase so difference btw that and a Deep Sea Seal could be somewhat akin to Ascended Super Saiyan (Vegeta - Dragonball Z Cell Saga) and Full Power Super Saiyan (Gohan - Dragonball Z Cell Saga). Hopefully boost wise though they are comparable so we can get a feel of just how powerful it is from Dorry and Broggy.
Worried that the Holy Jobbers won't be able to show us it's full potentai. That said I have an inkling that Kiringham being able to produce infinite portals of nightmares is tied to that as DFs usually have some sort of cap on them to stop them from being too OP. His doesn't seem to
Then there's Sea Floor Seals which you just know is gonna be hella filthy.
Imagine giving admiral level characters Sea Floor Level Seals. That right there imo is the potential of the Gorosei and why they seem perfect as endgame atagonists for me.
