Well Ichika will be strong if not somewhat overpowered. Ichika will be the teacher of the class and Chifuyu the headmistress of the IS Academy. Madoka will obviously have a brother complex that she will not even try to hide. Well Ichika will have already met Charlotte and has provided her a place to stay. Now Ichika will pretty much be the strongest beside Chifuyu. Ichika and Chifuyu are the titans compared to anyone. Both Ichika and Chifuyu are known as the invincible duo. Ichika befriended Tatenashi sooner and earlier along with Kanzashi. Before Ichika was Academy teacher he was student council president and his nickname was the Emperor or the Dragon

I'll be doing something knew with Ichika's IS given he's one those types who can't be beat.

In Japan the time is 4am and our young protagonist slightly long black hair and dark red eyes and at the moment is having a nightmare. His current age is 13 teen. "Nii-sama help me, I need you save me stop these people from hurting me!"

"Uh Why do I keep having these nightmares". I'm currently living by myself cause Chifuyu-nee is mostly working. When I asked nee-sama I keep having nightmares about a girl that looks like she could be my twin and Chifuyu-nee clone, she tenses up and tell me 'It's nothing but simple nightmare try not to think too much about'. I know nee-sama is hiding something cause she's quick to end the conversation. My sensei who teaches me martial arts taught me how to read body language.

"It's 4:30 am right now and I can't go back to sleep". I decide to contact Tabane about this and I've been waiting several days for her to answer me because I remember some vague memories in my childhood when I think about it I see myself with a woman that looks like Chifuyu but slightly older she seems to be in her early thirties or late twenties, but one thing is obvious is that whomever this woman is she clearly far more powerful than Chifuyu.

"Madoka" I say that name somewhat loud cause that name causes me to think about it and who is Madoka? cause for some reason when I asked Chifuyu does she know someone by the name Madoka I saw her eyes narrow and looked like I said something that could set her off.

"This doesn't make since for me to be kept in the dark by my older sister". I really am frustrated by this because I know in my heart we weren't abandon I remember somethings when I was 4yr being with a girl who always would cling to me she looked to be a year younger than me.

I decide to pull up my laptop and I've gotten a message from Tabane "Let's see what she's sent me". I mumble. The moment I click on the message I see a family insignia that comes from Japanese descend. That insignia brings nostalgia and then I see someone that I've been looking for a year." Madoka I've finally found her". I say with a bitter sweet smile I see her being held in a simple room with nothing in it.

"Well I'm coming for you Madoka onii-sama will save you". Now that I know where she's at I'm going to head to that location. From what Tabane tells me this group is known as Phantom Task. "The leader going by how she looks would be my mother". Well given who my sensei"!" Now that I think about it the one trained taught me a lot more than necessary.

I'm heading to the warehouse that me and Tabane use to meet at. A few hours have passed I turn around and see "that nut job of a scientist" thought in my head. Tabane "Ichiki how are shota kun!". She says with enthusiasm. I look at her with a serious expression and then pull out a photo of Madoka. Tabane facial expression gets tense. Tabane opens her mouth and asked "Ichiki are you sure, about this?". Ichika looks at her with his eyes turning silver grey color with a glow. Ichika looks at Tabane and tells her in a slightly darker tone voice with immense anger "Of course I'm sure, cause when I find those who has my imouto they are going to regret living". Tabane quickly thinks of that women 'Ichiki is defiantly that woman's son'. she thinks. Tabane looks at Ichika and says "Alright Ichika I have everything ready". Once she finishes her sentence.

A Day Later

Ichika lands in densely heavy forest and is wearing "Just imagine Venom Snake from Metal Gear Venom Snake but in black and Ichika has the same headband plus a Katana with a dragon on it two pistols with silencers and a HK MR762A1 extended clip and finally a tomahawk and hunting knife fifteen inches".

"Ichiki can you hear me?" Tabane asked me in my ear pieces. "Yeah I can hear loud and clear the sniper rifle you sent can see heat signatures and right now I see them getting prepared for a family meeting". I reply. Right now, I have a surveillance on Madoka right now and I'm waiting to see where they're going to place her. Thirty minutes have passed and now I'm making my move since the family meeting has started.

I see two guards and decide to through a rock in a different bush for a distraction. The moment they heard that direction earn them one bullet in the heart. I hurry to Madoka's holding cell and find her laying her head in her knees and her arms wrapped around her legs. I picked the lock to save my imouto and the moment I open her cell door she flinches and looks up.

In that moment our eyes made contact, she rubs her eyes as if she imagining things so I step forward and say "Madoka it's time for you to come home with me imou."I never got a chance to finish my sentence as she pulls me into a hug as she doe that I hold on to her and tell "we can continue after I get you out of here". As we head to the escape point I come face to face with one of my cousins Kana if I remember. I'm starting to remember that my sensei was actuality our grandfather who trained me. Kana looks at me with a smile while a look at her with a pure outraged look in my eyes.

"Ichika its been years and where's Chifuyu?". Kana ask me in sickly sweet tone. I look at Kana and decide to draw my katana and tell her "I'm going to enjoy this, Madoka don't let your guard down I won't let anyone hurt you anymore" I say that with a quick glance to her and her face is flustered and she replies "Yes nii-sama". The moment I return my focus to Kana she's in front of me with her katana drawn and the moment our blades clash, I simply redirect the direction of her katana with flick of my risk and counter with a side slashes. Kana jumps back but is slightly cut on her right deltoid. I have a small cut on my shirt.

Away from the fight scene we see a woman who appears to be in her mid-twenties to early thirties with black hair and dark red eyes watching the fight scene from the distance. "Interest my baby boy fighting one of our tops without being serious". As she watches she see Ichika's slightly board look.

Back to the fight Ichika has two slashes on his chest making an X and Kana is on both of knees breathing heavily and has a few slashes and stab wombs her right arm her is temporarily not working. Ichika looks at Kana and see the rest of the family coming to this direction and stop in their tracks seeing Ichika and a stealth fighter VTOL. Ichika grabs Madoka and puts his arm around her waist and pulls her to his body before leaving Ichika says "The next we meet again I won't hold back". As soon as he finishes Ichika and Madoka quickly ascend into the jet "Batwing similar to Arkham Knight". The woman and the rest of the family "Let them go I will be waiting, but for now let's test my son". As she says this Kana stands up healing from her fight and tells her aunt "Ichika wasn't taking me serious and didn't release his aura but I saw his eyes change before he left with that insect". Lady Orimura walks away thinking "Why did he want the useless girl?".

Izanami looks up as Ichika and Madoka leave in the jet and turns to Kana. "You've underestimated Ichika believing he would grow weak did you not Kana as I'm aware of your abilities and skills. You do remember Ichika was trained by my father Genzou and has kept up with his training". Izanami looks at her niece with amusement.

Kana looks at her aunt with some amusement. "Well I thought Chifuyu destroyed his potential but she didn't and what makes it more beautiful is that Ichika can contend against me it makes me wonder who else has been training him I wonder". Kana says with a lot of interest. An as she says this she sees her other cousin Chigusa who looks at Kana.

Chigusa decides to point something out to Kana. "You do know the reason why Ichika was matching you is cause he is master of all forms of swordsmanship and is a dangerous tactician to fight similar to are ancestor Sun Tzu. But my biggest question is why would he want the scorn of our clan who is the weakest?. "When Chigusa looks to her mother Izanami for answer she is walking away and stops and tells her daughter Chigusa "Ichika seems to value all his family even that outsider Madoka. What I do know is Ichika will become a Orimura the likes that none us have ever seen before". When Izanami said that a little of her aura releases. Everyone around her starts tremble from the shear pressure and potency.

Night Time

Me and Madoka are now at my house base of the fact I've been living by myself for eight months and since I returned Madoka has been clinging to me since we got home. The moment I used my debt card to buy some groceries worth nine thousand yen plus eighty thousand yen of clothes and underwear for Madoka. I allowed Madoka do use my debt card buy all that she needs. I'm currently online looking at my checking account and it seems from the stocks I've got to plenty money.

As I close the laptop Madoka comes into my room and from what I know its late. "Madoka its time for bed". I tell Madoka that and as I make my way to my bed I see Madoka follow me to my bed and joins me. "Madoka...yawn, what are you doing?". I ask her and she looks at me. "I'm sleeping with you nii-sama". She says that with a calm expression. "Ok Madoka but please be sure not to talk like that because it may cause a misunderstanding". She lays her head on my chest so I wrap my arms around her and kiss her on the head.

The Next Day.

Madoka's Pov.

As I wake up I feel a warmth and see my brother wrapping his arms around me protectively. This is the same brother that woman told me that he wasn't going to save me. My brother in many ways has an aura of passive but very dangerous, while Chifuyu and that woman are just dangerous. Ichika-nii aura seems control and focus.

"Nii-sama wake up" Madoka says to her brother. She sees Ichika open his eyes and Modaka stares into his eyes and her face heats up. "..Madoka are you ok, you seem to be heating up?" Ichika says while putting his forehead on Madoka's forehead and counts to three. While this happens Madoka face turns red.

Ichika's Pov.

Well this is fun teasing her. I really need to stop being influence by Tatenashi given her nature to tease. I should get washed up and make breakfast for us. "Madoka get cleaned up and I will make use breakfast and just call me Ichika-nii or niisan". Ichika tells Madoka nicely. "Yes Ichika-nii" Madoka says while smiling.

After we finish washing up Madoka using the shower by my room and me using my personal showers in my room. After getting done I've made me and Madoka some breakfast. Some chocolate chip waffles, eggs with onion, cheese and green pepper and finally, turkey bacon. "This is great Ichika-nii" Madoka says with sparkles in her eyes. Ichika was going to respond till he got a call from Chifuyu.

Ichika's final thought "This is gonna be interesting"

Chapter 2 will becoming out soon I will look through this and fix the spelling errors asnd you guys can help me if you want and I will be sure to but your names on the next chapter for those who help me. Constructive criticism is allowed but if you you don't like the story then don't waste your time. Focus on making your self better if you don't like this story. Everyone has their own idea of a story they would perfer to read.

Well Ichika will have his hair long like Venom Snake from Metal Gear V Phantom Pain but his hair style will be more like John Wick. Ichika will have very advance skills similar to Venom Snake and John Wick.

Ichika has two different auras one is a silver white like the "Ultra Instinct" but has immense amount pressure and power that makes it very difficult if not impossible to breath properly. The darker aura where he inherited from mother is like 'Think of Dragon ball heroes Cumber's aura" very dangerous and can causes some things like glass and other thing to shatter.

Ichika will have one of those Divine IS cores with along with Chifuyu, Madoka and the the other Orimura clans.

Ichika IS will have many different abilities and techniques but Ichika won't completely rely on his IS but will be a true master of combat. Madoka will be trained by her brother in terms of combat and skills.

Ichika's IS will be inspired by multiple gundam: Gundam Andromeda, Gundam Pamilya, Gundam Begonia, RX0 Unicorn Gundam, Sariel Gundam.
Madoka's IS will be Inspired by multiple gundam: Gundam Sinanju, Gundam Sazabi, Gundam Shin Musha.

In general he's making these IS Sentinel IS meaning these are not limited.
