Two days later you could see a 4 year old with blue hair and a ravishing charm that would make everyone want to pinch his cheeks standing in front of an enormous mansion. This was Murphy, he was wearing Itachi's anbu costume. He waited at the entrance when a maid came to the gate.
Maid : Are you lost sweetie?
Murphy : Im here for the bodyguard job…
Maid : Are you Murphy Neptune ?
Murphy : That's me!
Maid : But how can a little kid be a bodyguard it's a dangerous job?
Murphy : Its quite hard to kill me
Maid : Let me make a call, just wait here.
Murphy : Okay
Five minutes later Murphy was led to the door by the maid, she then showed him a door and told him that only him can enter the room. Murphy opened the door and entered the room. The room was a meeting room with a library on the side. 3 person were seated on the chair a middle aged man, a beautiful lady and a little girl. The two adults were looking at Murphy's body with greediness in their eyes while their daughter was simply curious about him. They were Kirio, Izumi and Momo Yaoyorozu.
Kirio : So you're the immortal child who is going to protected us, are you really immortal?
Murphy (coldly) : I've been killed continuously during one year so yeah. And what about introducing yourself first?
Kirio : Sorry I forgot to introduce myself, I'm Kirio Yaoyorozu and this is my wife Izumi and my daughter Momo. I am a politician and my wife is a scientist.
Murphy : I'm a Murphy and I'm supposed to become your bodyguard. Why did you choose me when you could have took any heroes as a bodyguard.
Kirio : Since the beginning of time mankind, men wanted to live forever and it seems you are able to, so I bought you from the government to discover your secret.
Izumi : Will I be able to take samples of him?
Murphy : So you really think you own me, money really made you dumb
Momo : Don't be mean to Papa and Mama
Kirio : Even if you use your other quirk with all the people here you will be captured and if you are able to escape I'll pay for someone to take your family hostage
Murphy leaked a little bit of killing intent : Do you really think I cant kill you now? Want to know the real reason I'm here? Its just because the government ask me to do something for them and in exchange they let me in peace, and you know why they didn't try to kidnap me even though im a child? It's because I have the ability to flatten your country if I wanted to. So if you try to threaten me with my family again I will make you feel despair by putting icicles in your wife and daughter's body.
Izumi : You wouldn't dare, because you would have nowhere to go after.
She then try to take a bit of Murphy's hair to analyze and research about his Dna. But when her hand got closer to Murphy an ice wall stopped her.
Izumi : You really think a little wall will stop me? Even if you are able to protect yourself now, you will be unable to when you sleep.
The ice wall then started to take the form of an icicle who grew and stopped just after touching her throat and drawing a little blood.
Momo : Don't hurt mama!!!!!
Murphy : So in this rotten family there is still someone who has feeling of kinship. Why don't you try to become a hero little Momo to balance the darkness of your family.
Momo : My family is normal there are no darkness. When im a hero I will put you in jail because you hurted Mother!!!
Murphy : Want to see the darkness? Do you even know pain?
Momo : Try but they are none and yes I've hurted myself when I didn't pay attention sometimes.
Murphy ( with the most innocent voice) : Kirio-san can I kill your daughter now if I let your wife research my body for a year and I collaborate with you for a year?
The room fell silent Momo looked at her father with eyes full of confidence. Izumi's eyes were full of expectation. Kirio reflected for five minutes.
Murphy : You see he is looking for the pro and cons and not thinking about you his daughter. Do you feel pain?
Momo : That's no true…
Kirio : 3 years and it's a deal
Izumi : Dear are you crazy, its our daughter. If we want his body we can always try but we only have one daughter. What would people say?
Murphy : See now. Contemplate pain accept it and know pain. Those who do not know pain will never know what true peace is.
Momo : I refuse to believe it
Kirio : If we have his secret we can always bring her back. And in the worst case we can say he killed her to flee and make another daughter.
Izumi : Sorry I've lost my cool I though with my feelings and not with my head.
Momo (crying) : That's not true
Izumi : Please do it in a painless way, i dont want her to suffer
Murphy : See now you need to become the number one hero to balance that amount of darkness. Now you know pain you can become a wonderful hero if you never forget it.
Momo : Are you going to kill me?
Murphy : Nah, I don't want them to touch my body with their repulsive hands, so you can live with them and let your pain and determination grow. Hey Kirio can you make someone buy me a house the nearest possible to U.A since I don't want to live with you nor protect you, I will just let a clone here and will only protect you from exterior menace.
Kirio : You destroy my family and you think im going to do it
Murphy looked at him in the eyes : Yes if you don't want to lose your life
Kirio : Okay but that's the only thing im going to do for you
Momo : Can I live with you, I don't want to be in the same house as them
Murphy : I don't care if you want just do it
Izumi : You're not going anywhere young lady
Momo : First you want him to kill me then you want me to stay here. No mother. I don't even know if I am really your daughter since you though about killing to live longer.
Kirio : Let her leave, they are only four years old they will come back and beg for forgiveness when they realize they will be unable to live without grown up. And our daughter will not forgive us soon.
Murphy then used the illusion mist techniques to make himself look like a 20 years old version of himself.
Murphy (sarcastically): Oh no I am a teenager and i cant buy anything. Its so sad Alexa play Despacito.
Kirio : But you will need other people to live with you, you can't live alone
Murphy : I have a mother and a brother…
Kirio : Leave your clone and never come back here.
Murphy then made a water clone and left without the room without even looking back. Momo ran after him but looked at her parents upon leaving the room then followed Murphy with eyes filled with tears and determination.
