[Latest WN Arc] What kind of mothership do you think Hiro will get and how?

Hiro has expressed purchasing a bigger mothership for their crew, and for the Antlion to dock in as well for repairs. Where do you think they will buy one, what kind of ship, and will they trade in Black Lotus for it?

Personally I doubt Hiro trades in the Lotus, and I think he'll get one in Windas, not from the Holy Empire.

As a requirement, Hiro needs a big enough ship to hoard his kills while docking all his other ships, as well as having strong enough shields to defend against villains like Marie. I also think a war arc is nearing and a pirate luring fleet will be woefully inadequate for it.

So I think he'll get a mothership half the size of Serena's Restalias/Lestarius. Big enough to dock all his ships while being fast enough to not need several escorts all the time like Imperial Battleships.

It's also possible that after this trip, he marries the current harem and gets gifted a state of the art mothership from the three noble families, given his job.

What do you think?
