we zoom in the ironblood base where Bismarck was arguing with purifier and it continued for twelve hours

Bismarck:why should we ally with you

purifier:if you ally with us your sister will be spared if not then he will make you

Bismarck:he as she looked to see a person in black armor with a manta ray helmet

entering her office

purifier:ah black manta your here

black manta:im here so what is the reason you arent helping us Bismarck

Bismarck:i want your promise you wont target us

purifier:we wont if you follow our commands and also black manta will be staying at this base to help you

Bismarck:just who is he

purifier:do you remember FN

Bismarck:wait isnt he a famous thief that target the azur lane convoys

black manta:yes he is also my father

purifier:Bismarck i would like you to meet the son of FN HIMSELF BLAGOJ

As blagoj removed his helmet to reveal himself Bismarck was suprised to see this the son of FN IN league with the sirens

Bismarck:why would you join the sirens

both of them were laughing at this as she was confused

blagoj:im a mercenary for them

purifier:he speaks the truth he will be helping the crimson axis in their mission

Bismarck:understood is there anything else should i know

purifier:if enterprise is spotted you will give him permission to kill her or injure her sevearly

Bismarck:why

blagoj:she killed my father so she will die

in the end of the day the deal was made as blagoj was given his own room as his suits were kept in the sub as he was helping Bismarck with the paperwork as she finished all of it

blagoj went to the bar to get a drink along with him was Prinz Eugen as he was drinking his beer and

went to sleep to prepare for tommorrow the meeting between the ironblood and the sakura empire will begin and soon the war will start
