Chapter 20: Two paper fans

"Make the heavens tremble…. Raikou!"

After I released my Shikai the clouds in the sky turned gray and my body was wrapped in lightning.

"This one of my Shikai, Raikou creates lightning around me and let me do things like this" After I said that the next second, I was behind everyone without them noticing.

"I can move really fast thanks to him and also I can create lightning to trout it to my opponent," I said as I send lighting with my spear to the other side of the field creating a small explosion.

"Excuse me why do you call your power "he" and "him"? Asked Kenshin

"I know that sounds weird but its because each one of them has their own personality, and even if they are a part of my soul, I consider them as their own persona while they are a part of me, it's a little difficult to explain, but you can think that its something similar to a sentient Quirk"

"Izuku-san you are too OP, this power alone can help you to be a top hero, but you have 7 of them and that weird magic of yours, you're a complete cheat." Said, Kenichi

"Hahaha well even if I have many powers, it has its own downside," I said without being polite.

"Why? Having more powers should be better, right? Asked Kenichi

"Think about a minute you damn karate kid, if he has many powers, he has to train a lot more with each one of them, also he has the risk of becoming a fucking Jack of all trades master of none, we had our Quirks for a long time and we still have to find things we can do with them, so imagine how big is his problem." Said Katsuki

"Why do you always pick a fight with me?" Said Kenichi with tears in his eyes.

"As expected of Katsuki-kun a very well detailed explanation." Said Kenshin ignoring his brother since he knows that this is the way Katsuki shows his tough love.

"As Katuski said, it hard to not become a Jack Of All Trades, and knowing what is the best moment to use each of them is hard, it cost me an arm many times to learn this lesson," I said sightly shiver remembering my training with grandpa.

Everyone was frozen when they heard my words.

"Izuku-kun what you said it's a metaphoric way to say it was hard, right -de gozaru? Asked Kenichi with a pale face.

I shake my head at his word "Nope, I mean literally, I don't know how many times I lost my arms training with grandpa for doing mistakes"

"Oi oi oi, what kind of training did you do? That is savage, how do you still have your arms if he cut them? And you are not going to do the same with us right? Asked Kenichi with a horrified face.

"Most of my training was to fight with grandpa and since he had plenty of battle experience its normal to lose a limb or two while fighting, and we use a technique named Kaidō that can heal everything as long you don't lose, so he just reattached my arms, and don't worry only if you want I would do that kind of training," I said with a calm voice.

Kenshin and Kenichi had relieved faces knowing that I would not cut their limbs in training but Katsuki had a frown on his face.

"Oi damn toothpick you still haven't shown us everything you told me that there is a second phase of your Shikai if my memory doesn't fail me the name of that is Bankai, why you haven't shown us that?" Said Katsuki sightly angry.

I just made an awkward smile "Well it's something embarrassing but I haven't achieved Bankai with Raikou, he told me that I need to get more experience to get it hahaha"

"And what about the rest?" Asked Katsuki.

"Well, I can use 4 of them but it's not the time hahaha they are too powerful and I don't want to destroy the training field hahaha," I said with an awkward laugh

"Don't give lame excuses and just showed us you damn Toothpick!" Said Katsuki with an angry voice.

"I promise I will show you after you complete your training so please be patient," I said assuring him that I will show them the future.

"All right Toothpick!" Said Katsuki

"Well let's start today's training, yesterday we mainly focused on the core, so today's main focus will be the muscles below your waist, so first we are going to start with one of the most important muscles in the body, the gluteus maximus," I said with a serious expression

*Pff*

*Pff*

Katsuki and Kenichi tried to contain their laughter the best they could.

"Hahahaha Izuku-san you don't have to be so dramatic while you are telling us to train the buttocks." Said Kenichi almost falling from the laugh.

"Hahaha I knew that you had to have a fetish but I didn't know that you will reveal it like that, maybe the reason you never had a girlfriend was that they didn't have a big-"Said Katsuki laughing but I interrupted him

"No horny smash!" I said as I hit him with a paper fan that I materialized.

"How mature of both of you, I was expecting this from Kenichi but not from you Sparkles," I said half annoyed.

"Why is always me!!" Said Kenichi with a desperate face.

"I'm being serious, the gluteus maximus has long been recognized as one of the strongest muscles in the body, playing the most central role in our ability to walk upright and stand erect for long periods. It also helps us to keep us from falling forwards and with the assistance of glutes minus and gluteus medius which prevents us from toppling sideways, so don't take it as a joke" I said with a serious face.

"Well it makes sense since from what I saw on T.V your girlfriend has bigger che-" Said Katsuki but before he continues

"No horny smash x2" I said as I smacked two paper fans on his head.

"Hatsume-san it's not my girlfriend also don't be disrespectful to her" I said very annoyed.

"Dude I was just joking, chill out" Said Katsuki

"Whatever let's just begin with the training, first you are going to do 500 reps of the Cook Hip Lift exercise," I said pointing out what the first exercise was but no one does anything.

"Excuse me Izuku-kun, can you explain to us how to do that exercise I have never done it before." Said Kenichi quite apologetic.

"Oh sorry I didn't realize that, well first you need to lie on your back with your hips flexed and feet lined up with your shoulders. Flex your hip by holding one knee to your chest. Lift your toes off the floor and perform a bridge from one leg. Hold this position for 2 seconds then return to the starting position. Lower your body back before repeating another repetition on the same side." I said while demonstrating how to do the exercise "The is any doubt about this exercise?"

Everyone shook their heads and started to do the exercise. Kenichi was doing pretty well since he did train the muscles around the legs quite often, Kenshin was just having minor problems, but Katsuki was having a hard time doing it since he mostly trained his upper body, and to be honest, I was quite happy, that serves him right for being rude to Hatsume-san.

After a couple of minutes, everyone finished the exercise, after that, we did a couple more exercises to strengthen the gluteus maximus. Then we trained the quadriceps and the iliopsoas which are two of the biggest muscles in the legs.

"Okay guys that's it for today you go to the dining room to eat, I already prepared the food for today, it's on the fridge so just heat it on the microwave, I need to go to the lab to finish something, remember to go to the spring so you can recover faster," I said to them before leaving.

As I was walking to the S.R.D.I. I started to laugh "Hahaha today's training was pretty fun, I bet that they can barely walk, this is getting funnier than I first thought, I can't wait to start the fighting training"

As soon as I reached the lab, I started to try to recreate the regenerative serum and the Data-gathering Bacteria, but again I was not getting any results on this. Well like they say science it's 1000 failures and 1 success but after that success, it gets easier to recreate. After a few hours of trying, I decided to take a break to do some light exercise to clear my mind. I must say that it's very fascinating how the mechanism of the Data-gathering Bacteria, it's like a hive-mind that links each of the bacteria, but what is weirder is how they can communicate with the user.

When I reached the training field I summoned my spear and increased the gravity around the training field 3 times. I started with the basic movement, thrust, strike, and cut. First I did it in the slower way possible to have absolute control over them, and progressively increase the speed.

After a few minutes of doing that, I started to do some advanced moves like using acrobatics at the same time as my spear, doing some faints, some spin attacks, etc. After that, I continue with incorporating Reiatsu into my attacks, which is "harder since I need precise control over it, it's not just putting a lot of Reiatsu in my spear, distribute it in equal parts around my spear so the movements don't get stiff, from time to time it's necessary to change the balance so I have to do some calculation in my mind.

After two hours of doing this light exercise, I decided to stop and go to the lab after taking a shower. I feel that the guys were watching my training but if they don't talk to me I don't feel the necessity to talk about it.

After half an hour I was already in the S.R.D.I. lab to start again my investigation. "I wonder how long it would take me to recreate the serum" I just sighed thinking about how stressful would be the next couple of weeks.
