MUMU

• Before he was sacrificed, he was relatively healthy... if a little wobbly on his feet. And about as healthy as a kid meant to be sacrificed in an already neglectful isolated cult could be.
• After, though? He lost all strength in his body. From 15-17, Mumu was wheelchair bound, and only managed to get himself standing on crutches late 16-early 17. The first time he ever walked post-sacrifice was a couple months before he turned 18.
• These days, Mumu has enough strength in him to be relatively active.. but there's days where he can't walk, and he where he is bound to a wheelchair or cruches, much to his immense displeasure. 
• Despite all of that, he is extremely agile. He can run around, bounce off walls, climb, all with ease. He also has breakneck reaction speed, and is up there in the fastest among SH4DE, able to dodge oncoming bullets after the trigger is pulled.

• Mumu looks like he has not eaten in a decade. He looks like he should've died from starvation years ago, and the maggots should be begrudgingy feasting on what there is of his flesh, because he has no muscle. You can see the bones in his arms and legs, just how sunken the skin around his eyes is, and feel the ridges of his finger bones when you hold his hand. And yet, he manages to be stronger than the a good percentage of people out there.
• Chipped nails. All the time. 
• White eyelashes and eyebrows.
• Pupils are in the form of four-point light blue stars.

• Mumu wears an obsidian band ring that blends in with his gloves. It looks like a regular ring, but has a button on the sides that, when both pressed twice, causes a small, but blinding flashbang. Most effective against those looking directly at it.
• On the headband that holds up his hair, there is a red bow with a blue star at it's center. The star on it's center is not an ordinary accessory, rather it can be detached and, with a flick, transformed into a ninja star. That isn't all; when thrown, Mumu can teleport to it's landing location, or by use of his watch, can teleport to it's location whether it has landed or not manually. He has several other stars like this, and can even plant them in different locations to teleport to different locations quickly.
• Several USBs he can plug into different outlets that allow him to do one of two things: 1. quickly download any designated data, or 2. automatically bypass security and allow Mia and/or Utada into the system.
• A watch that has several other functions, such as...
      > Displaying holographic screens. Maps, messages, layouts, cameras, time settings, etc.      > Send distress signals, and sometimes, can disrupt signals or invade them to listen in.      > Trackable by Utada & Mia.

Mumu was never educated in anything for the first 15 years of his life. How to read, how to write, multiplication, division, Hell, he didn't even know how to hold a pencil. He learned how to add and subtract through observation. The only thing he was taught was how to obey every command, and that he was a gift for the Gods.

When he was sacrificed and sent into that god-awful pocket in the void, occasionally things would fall through rifts into his little bubble. Books, old instruments, devices, toys, broken glass, you name it. Mumu was desperate for anything to keep himself busy, to distract himself from the horrors around him. So, he tried to teach himself how to use everything that came and went. Sometimes, he'd have what felt like years with the things. Sometimes, he'd have an hour before the void decided to swallow it whole. In his early months inside that pocket, through both memory of his life in the cult and pattern recognition, he taught himself how to read. He'd gotten lucky with the extremely basic books that came and went, but unfortunately, a lot of them were in different languages from the dialect he was used to. He would take apart phones and tablets, headphones and watches, trying to figure out how they worked. Mumu was never able to dismantle that clock that ticked for eternity.

When he got out, Kyu enlisted him in online school. More often than not, Mumu barely had passing grades. He went from various different levels before finding what he could handle. After the first struggles of trying to teach a traumatized, starved teenager how to do basic functioning, and after countless weeks in the hospital, he finally got a hang of things. From there, it was uphill. Mostly. There were times, many times that Mumu struggled, especially with complicated topics. Once Lady Kyu decided to have him try going to an in-person school she thought was reliable, his grades went up thanks to the assistance he got from his beloved friends and less-unstable brother. Much to everyone's surprise, he took many classes on psychology and linguistics, finding it absolutely fascinating learning how the mind worked. He wanted to know what was in all those books that he hadn't been able to read.

These days, Mumu is an exceptionally fast learner. Frighteningly so. He still struggles with basic math aside from what he memorised, and retained jack shit in the science department, but he knows what he has to for his job.

• Unless we're counting the odd occupations he 'took up' for spying.
• The only other thing he did was dip into music, and even took up a career as a singer, becoming one of the largest and well known artists to this day... 
• up until he was exposed for possibly being a spy---by extension murdering people---and his career fell apart.
• Thankfully, he did have his job as a spy to fall back on, and to this day he's stuck with it.
• He never worked with an agency other than the Council before. Although these days, he sometimes pops up to "collaborate" with agencies as a temporary member for certain missions that pique his interest, and usually, it is for the sake of collecting information on that agency as well. One of his jobs is to monitor them.

• The fact he survived at all is an achievement in itself, honestly!
• Becoming one of the largest idols around, especially in such a short time.
• ^ He had an enormous impact on pop music, especially when it came to mixing languages. His music was a source of comfort for many, and even after the allegations, people still applaud him.
• His expertise as a spy. Becoming a spy at all in his condition was one thing, but rising to be so well-known for his skill? That is a whole other thing.
• Being able to annoy people as much as he does (purposefully) should be considered an achievement, too. How does he do it? I write him, hell, I made him, and I don't even know.

• Can't eat normally, makes him physically ill. (Not anorexia, but similar.)
• Can't gain weight.
• ADHD, C-PTSD, PTSD, CIPA (partially treated), manic depression
• ^ His CIPA (congenital insensitivity to pain) is partially treated. After going several months without dying, he can begin feeling pain, but only from hard hits or deep slashes. (He's slightly masochistic (not sexually) because he sees it as a reminder he's actually human.)
• Extreme moodswings, hyper aggression and impulsive suicidal tendencies.
• Dysmorphic to the point of covering all mirrors. (Not just him on that level, but, you know.)
• Misophonia (decreased tolerance to specific sounds, in this case: ticking, clicking, chewing, knife sharpening/similar)
• Phonophobia (fear of loud sounds), Chromentrophobia (fear of clocks/time), Thanatophobia (fear of death/dying), Noctiphobia (fear of darkness), Autophobia (fear of being alone)

• Mumu has a lot of basic knowledge about a lot of things. He can execute most things at an amateur's level at least, and while there is very little he is confidently professional level at, there is one thing in particular he's mastered that makes him almost unstoppable;
• the art of bullshit.
• Seriously, 80% of his acting, in every way, hinges on him bullshitting everything he says and/or does. Doing something with confidence and certainty, even if you are terrible at it, gives the impression you know what you are doing. That's all you need as a spy.
• Other than that, he has mastered disguise, especially with the aid of Utada's disguise tech that helps him look less... freakish.
• He has also mastered psychology and sociology, especially manipulation of both the former and latter. He can play just about anybody like a puppet on a string.

• Fashion, cosplay, sewing, anything involving those things.
• Learning new things.

• Don't even talk to him about hacking. Or anything involving engineering or technology that isn't the absolute most basic repairs. He can work complocated tech, he can't do anything else with it.
• He won't go anywhere near a kitchen or anywhere that food is involved.
• Sorts. Sports of any kind, except maybe badminton. You will never get him to take time out of his day to learn even the basic rules.
