We zoom in the north where a bismarck sister tirpitz was based there as she was patroling the area she saw a large siren armada

 heading for her position as she engaged the sirens on the other side of the area are federation and thunder being locate there

 as they heard the sound of guns firing  thunder knew whose guns belong to her seeing that she will be overrun thunder rushed to reach tirpitz

Thunder:commentary:we need to reach tirpitz before its too late

Federation:lead the way man we will follow

Rizky:understood

As they rushed forward to  to reach tirpitz we zoom as she was fighting the siren armada on her own sinking many of them untill their reinforcements arriveed before they can kill her the sounds of gun fire and explosions are heard 

as she looked to see thunder federation and rizky arriving and destroying many of the sirens and before the next wave will come they introduce themselfes federation and rizky it went like this 

Tirpitz:good see you thunder who are your frieunds 

Thunder:commentary:this is federation a stealth aicrafted carrier and rizky a space battlecarrier

Federation:nice too meet you tirpitz im federation

Tirpitz:nice too meet you boy

Rizky:im rizky nice too meet you 

Tirpitz:nice too meet you so what happened

So federation explained to her what happened after the orochi was sunked and being sent to the northern parlamented to destroy the siren presence to defeating the observer sirens ect but before they can continue the third siren wave

Arriveed as they arriveed they begun to engage the enemy forces wipeing out many of them as the final ships were sunked to the bottom of the ocean thunder asked tirpitz what she would do she told them she will help them in

 their mission as they agreed they begun to sail towards the northern parlamented to wipe out the siren presence being there

As the three of them thought things are becoming more intresting
