Non magi and other people witnesseded a talk between flown akatsuki and yaeka akatsuki a few months after the great fight of viritas versus the rest of world, not much was taken but the main message was passed, and rumors created about it, just like years ago when the demon toji (post) tainted the honor of unarmed combat, 30 years later in future another figure shows up, causing so much mess, and as the fool old man he is he cannot let it be.

"Well as expected, i fail in change your mind" he says fixing his hat.

"I tried put sense in you i failed, humanitytried end your 'beautiful' path they also failed,, i was worried this would come...
and i'll leave to the only person i know is strong enough to make you understand all i meant." he says.

"Be prepared." he says putting his hands on his back and leave.. a glimpse of a cyan shield on the backpack.

Quote:

I will finish what I started.

I will give you the shape you so desire.

I made you bleed beautifully before,

gave you agency you didn't have.

I will do it again, dear Uncle.

Over and over, until you understand.

Until you see the beauty that I do,

in these dances with death.

People witness the fight, that was a true display of martial arts maestry from both sides, to someone win the other must lose....

Yaeka ends up as the victor at the cost of one life, Captain serenity, and almost the full lost of flown memories, as well his retirement from fighting.

the outcome was that captain serenity outmached yaeka, and instead of finish her with a punch... he spared her, which she took the chance and pierced his knee, declaring her victory, it was agreeded by both however lost would retire, and flown took his word seriously, yet...

Something else happened on the after battle, the heavy depravation of blood supply on mind caused brain damage for flown, that  lost parts of his memories, Milos managed bring from inside the old man heart his manifestation the himself captain serenity for a last goodbye while was being lost from the old man mind:

his last words were to keep promise , to retire, as said to yaeka, and have more faith on himself, as the old man created him as figure to inspire and be, when in the end he was all that, even if dont saw it.

One thing is clear, is a dark day for the martial arts, as his use as weapon for any goal anyone may have... kept unpunished.
