After Sodai negai step father's death, aka emperor yoshiro. He was very pissed but he calmed down, he was on the mission to destroy the allies naval base. He was in his flagship main battleship, named the shogun battleship. It was larger than the other 4 shogun battleship.

Sodai negai POV

I was sipping my tea while watching the sea.

Me: when will the war is over.....

Suddenly the sailor comes in

Sailor: commander. We almost to the enemy naval base in 1 hour.

Me: good, tell our fleet to prepare our weapons.

The sailor nodded and bow, and he head out the bridge to contact the ships to ready the battle. And I spoke

Me: hey shogun, when will the battle end? Should you can rest.

I talked to my ship, I know is a ship, not a person but I consider it as my trustful friend.

Me: yeah, I hope the war is over my friend.

Sunddelny, 500 allies planes from 50 carrier appeared out of no where. Surrounded them.

Me: fuck.

I grab the radio and contact all of my ship in my fleet

Me: BATTLESTATIONS!

The 50 tanks was charging to the carriers but shotdown by the allies destroyers. 100 destroyers just destroyed the naginata cruisers but they sunked 20 of the allies destroyers.

I look above and 30 bombers start bombing toward my ship. I spoke to my radio again

Me: ALL CREWS ABANDON SHIP!

Most of the crews start abandoned ship and returning to the Japanese naval base. The 4 shogun battleship holding them off while my flagship shogun battleship was sinking and sailor barge in

Sailor: Commander! You need to get out of here!

Me: No! You guys go, I will sink with my friend!

Sailor got confused about the 'friend' word but he shrug it off and heading toward the boats, abandoned my ship. I was sinking slowly and I sigh

Me: LONG LIVE THE EMPIRE, TENNO HEIKA BANZAI!!!!!!!!!!

I push to full throttle, speeding up fastly and the shield appeared in front of my shogun battleship

My ship and I ramming the 25 carriers. Half the carriers destroyed but my ship is heavily damaged. The destroyers finish my ship off and exploded with me. I Black out and I seeing dark place.

Me: this is how I die? As 7 years old Commander.... Comrades... Fight for our glorious empire...

I was in the dark void and nothing was here. Suddenly a light appeared in front of me

Me: what the?

I start to go closer to the light and it getting brighter. I used my hand to cover my eyes from the brightness.

When I open my eyes. I was on the island,and I see my shogun battleship. Repaired and no damaged.

Me: am I giving a second chance to live this world...? I think this world is different...

???: yes it is shikikan~

I shocked and I grab my katana, I ready unsheat my katana when I jump back away from the person. I look at the figure and she a female with a Japanese clothes I think

Me: who are you?

???: ara~ my shikikan forgot about me~

Me:huh?

I got confused. But suddenly, thousand of blue cubes thingy appearing from my shogun battleship. And appeared behind her as her rigging.

???: my name is shogun~ IJN shogun~ remember I'm your friend?

I was shock. My friend, the shogun battleship have a human form. She walk closer to me and hugged me. Her breast start touching my face as I blush a bit and look away

Me: can't believe you have a human form shogun

Shogun: yes shikikan, now I can do anything for you~

Me: heh alright.

Me (thoughts): I think my shogun is a yandere... Fuck....

Shogun: shikikan~ let's go and let's explore this new world~

I nodded and rigging disappeared when the thosuand of blue cubes appeared, forming the shogun battleship again. She grab me and carry me, bridal style and jump on my ship, I blush a bit and shrug it off, i jump down from her and we head to the bridge, it was still the same but some others are different.

Shogun: awaiting orders shikikan~

She smiled at me and I feel she really a yandere and I need help. I put the speed 1/2,exploring this the largest ocean.
