There was a letter for lamgiabao2017 when he arrived in a new timeline, where Kevin was a Vietnamese Navy's Sailor instead... And lost his memories.

'Ahoy, Lam me bucko! Ye might be confused as t' see why I 'ave become like dis, but it's all thanks t' me amnesia 'n the World Government's inability t' capture me 'n me crew 'n me fleet, but I assure ye, me hearty! It's me, but now free 'n wit' the freedom t' do wha' I wants!'

'Ye 'ave wee t' worry, about 'cause I still couldn't find Madlantis, but it appears dat I'd end up in the Yandere Crossover by the Admiral Red Beard Phoenix! Perhaps dat shortcut will give me both treasures 'n booty, 'n a shortcut t' the Madlantis! 'n so, I gathered me bestest crew 'n me finest fleet, 'n made me journey t' the true cabin o' pirates!'

'Worry nah fer me, me hearty! If the Government Fleets can nah defeat me, 'n o' course, nah even me former maties, neither can those Lust-Filled Lasses! When I come back, I shall tell tales 'n bring ye some treasures t' show, jus' don't arrest me, 'n we'll be all good!'

'Dat's all I can scribe, remember me as Cap'n Knot-Tying Kevin the Sparrow o' the Seven Seas! Yar har har har!!!'

The Kevin's Raven Fleet, including a few Retrofitted Ship-of-the-Lines of various types, alongside Pre-Dreadnaught and a few WW1 Ships, fully loaded all carried the Red Flags, with a White Raven with a Skull...

Now that he's gone... the World Government can finally be rebuilt and continue as usual... Except with people now not having to worry about a Terra Invicta War.
