I woke up the next day feeling well rested and did some stretching before noticing a note beside my bed. I walked over to the note and saw it was from the alternate me.

Dear me,

This letter is to explain the two new power I gave you.

First one is the ability to expand any part of your body like the Super expansion jutsu from naruto so it's quite self explanatory.

Second is that I gave you more control over your bloodlust such as you are able to make it interact with objects and seen by enemies instead of making them only feel it so that's all I have to say. Good luck making the food for the party, there's still another week before it starts.

By you.

I became excited about the new powers that I've been given before sweatdropping realising he didn't told me how to activate my new powers so I headed to a forested area near the gremory estate to test it out.

A few minutes later, I'm standing deep in the woods near a clearing with a lake nearby so I decided to try the body expansion first.

'So if I'm right I just have to imagine it becoming bigger right?' I then imagine my arms increasing in size to see that it did increase in size before trying to change it back to normal size and succeeding.

Afterwards, I tried expanding the other parts of my body and my entire body and I managed to grow to a height of 50m before feeling extreme pain from the size expansion and collapsing from the pain for a few hours.

"Well at least I know my limit now." I told myself after waking up and after checking the time I decided to try out my new control over my bloodlust before heading back to rest.

1 hour later

"..." I became silent as I stare at the massive amount of destruction that I managed to create after testing my bloodlust. Around me, it was just barren ground in a 20m radius where even the lake was completely destroyed.

What happen was that I make my feel murderous and I can see a red aura form around me and I decided to try shooting it so I point at a tree while making a gun gesture before imagine a bullet firing out of it which to my surprise, a red ball of aura the size of a tennis ball formed at the tip of my finger before flying towards the tree and destroying the trunk.

I then decided to do a few more test and basically conclude that I can use this bloodlust aura as anything I can imagine such as if i and if my bloodlust is at its peak, I can wrap it around me to become armor and the apparence of this so called "armor" is shocking as it basically make me look like carnage from marvel with a meter Long spike sticking out at the end of my arms. I then called this berserk mode and decided to run wild which to my current position now. "Well, that was fun." I told myself before deciding to call it a day and went back to the gremory estate.

For the rest of the week, the only thing I've been doing is sparring against surtr to get used to my new powers and testing new recipies for the party that's going to happen which I have surtr and for some reason millicas to taste test the dishes.

Flashback

I just finish sparring when th surtr and decided to bake some pastries and while waiting for it to bake finish, I saw a mop of crimson hair floating behind the countertop so I went towards the counter and look behind it to see a kid squatting on the floor, trying to hide from me.

I just chuckle and pick up the boy and put him on a stool.

"So what's your name kid"

"I'm millicas gremory, Son of Sirzechs gremory and Grayfia lucifuge."

"Ehh so your their child huh. Nice to meet you millicas my name is Zheng Yu but you can just call me ZY."

"Hai ZY onii san."

"Hahaha ok then I won't ask why your here since your probably just bored from studying all the time so you want to eat some pastries?"

"HAI onii san!"

Flashback end

So from then on whenever millicas has a break from his studies, I would make him a snack everynow and then which makes sirzech jealous since millicas is spending more time with me then sirzech.

Currently I'm packing the pastries I've made for Rias and the rest for the rating game thats happening tomorrow when grayfia entered the kitchen with a cardboard box big enough to fit a person inside.

"ZY sama, I've brought the box you ask me too get."

"Ah thanks Grayfia, it's just what I need."

"I'm sorry to ask but what do you need the box for?"

"Oh just a prank I'm going to play on Rias and the others which I also need your help with."

"Ok then ZY sama, what do you need me to do?"

A hour before the rating game starts

3rd person POV

There's only an hour before the rating game start, everyone in rias peerage is nervous about the match when suddenly Grayfia enter the room pushing a wrapped up box into the room.

" Eh grayfia, what is the box for?" Asked Rias.

" it's a present from ZY sama, rias sama." Replied Grayfia

"Ehh from Senpai!!!" Exclaimed issei who then walk over to the box and open it before seeing what is probably one the worst thing he have ever seen.

When issei open the box, Zheng Yu burst out of the box with a gift basket filled with pastries and treats while only wearing a speedo and an apron covering his body.

My POV

"SURPRISE!!!" I screamed out as I burst out of the box scaring issei and the others while I look at their reaction while having a grin on my face. The girls are looking at me with their faces flushed red because of my attire while akeno is seductively licking her lips while kiba silently chuckle at the situation and issei is lying on the ground recovering from the shock I gave him.

"What the hell sempai!!! What are you doing in the box anyway!!!" Yelled issei as he got off the floor. I then climbed out of the box and pass the gift basket to him.

"Well it's a prank of course and I also want to say good luck for the rating game so here's some food to calm the nerves alright." I then took off the apron and wrap it around my lower half before leaving the room.

"Wait Senpai, aren't you staying here with us for awhile before the match start?" Asked issei.

"Nope, there's something Important i need to do so enjoy the treats and good luck! bye."

I then wave goodbye at them and left the room before asking Grayfia to teleport me to my room so I can change to an appropriate attire.

Omake

"Why am I dealing with this kind of bullshit..." I asked myself as I fell through a dark void while in my birthday suit. If I remembered correctly, I was in the middle of a shower when a hole pop up underneath me and I just fell through it.

"Hahhh, wonder where this would take me?" And just as I said that, the world suddenly brighten up and I find myself standing on top of a ship with a huge old man with a white moustache holding a large bisento standing beside me. My eyes immediately widen as I recognised who I'm standing beside.

I then quickly took in my surrounding and saw it was a battlefield in front of me and that was when I realise where I am now before turning towards the old man.

"Yo whitebeard, do you have any clothes for me to borrow? In exchange, I will help save ace alright?"

"Gurarararara! What do you think you can do brat?" Ask whitebeard as a men came and pass me a white shirt and a pair of cargo pants.

"Why don't I show you then old man." And with a grin on my face i jumped off the ship and immediately start to grow even bigger then oars jr and changed directly to berserk mode. And quickly pulling out my sacred gear and extend it into a staff I screamed out in a demented and demonic voice, "HAHAHAHAHAH, TIME FOR ME TO HAVE SOME FUN!!!"
