"Time to play some Azur Lane"

Says Wolfgang. Wolfgang starts playing Azur Lane, so he boots up Azur Lane and starts playing. Wolf checked the docks, and he tapped one of them to see that she's upset

"Huh... Strange" Wolf says while suspecting about the upset behaviour on his ship, then he shrugs it and says

"Nah, maybe I neglected her too much"

He checked the others to see that she is also upset to him too

"Okay..." Wolf says then checks the others and others and so on until he stops to one ship he did not check

"Belfast"

When he tapped to her, It shocked him. Belfast's affinity is 666, and He knows that the ship's max affection is 200, but Belfast's affection is at 666

It got him a little scared on what he saw

"I-Its just a bug r-right?" He asked while he's shaking and sweating

When he tapped her, her response is what shocked him

"Its no bug, its how much I love you, master~ So much that I made a deal with the devil himself~!" Belfast replied to Wolf

After her dialogue, Wolf freaked out and he's scared even more

"Y-You can understand on what I'm saying?" He asked before tapping her

"Yes, Master~ it tickles~" she says while giggling

Wolf felt scared a lot for a girl to be more self aware than ever so Wolf unlocked her, then went to retire her, But when he tried to press the retire button, its not available, so pressed the back button, but it directed him to Belfast again

Wolf got scared on tapping her again, so he did nothing. But Belfast decided to talk without being tapped

"What's wrong, Master? Why did you try to retire me? Am I not good enough for you? Or you have someone else instead!?"

Wolf was living alone, and he doesn't have anyone with him, not even a girlfriend. But the Belfast situation gets him nowhere, so he changed his account, and made a new one

After the tutorial and the starter ship choosing. Instead of the starter ship which everyone has as their secretary. It was the Belfast with the 666 affinity

"Now its just you and me, Master~ thank you for making this account" She told Wolf

God knows how much he's scared for what he is seeing and He cannot get rid of her in the game, no matter how hard he tried, and it scared him very much. He only has one option left. He uninstalled Azur Lane, then he sold his phone to buy a new one. He got back home with a new phone, and did the preparations. Once he's done prepping, he saw the app that has the cursed Belfast. Azur Lane. Wolf decided to ignore it and download another game he used to play. Fate Grand Order. After Wolf finished downloading FGO, then entered his recovery code. He saw his old servants, Mash and Tamamo. Wolf decided to do today's ember farming, and its going well on what he's playing. So he decided to play FGO instead of Azur Lane from now on

A day later, he boots up FGO once more to do ember farming, then he went to pick a support servant. Once the battle starts, he saw someone that he doesn't wanna see so badly

Belfast

Belfast is the support servant instead of someone else, and he look to see Mash and Tamamo's face in despair around Belfast, while Belfast keeps her smile. Her Dialogue shocked him since he can understand Japanese

"I killed that pest, so I have to take over instead, master~" She explained

He never knew she can jump onto the games, and he tried choosing their skill, but they were stunned when he pressed the attack button, he saw that Belfast can attack the embers
He use her cards, and she took them out, then the farming ended

"How?" Wolf asks

He returned to the main hub on fgo to see Belfast is included in the hub. He checked my room to see that its covered in blood, including belfast

"Lovely room, master~"
