Zaha Sanko

Zaha Sanko (ザハ＝サンコ, Zaha Sanko) is a young man who travels in space with the Package of Darkness, Avakian. Someone said that having Zaha's bones will grant any wish they desire, so now Zaha is trying to find out who that person was, while being targeted by every person in the universe.

Appearance
Approximately 190 cm (~6'3" feet) tall, with a slim muscular build. Commonly seen wearing his skin of darkness when traveling outside of his ship. He is sometimes shown wearing t-shirts with sci-fi monsters on them, an example of which is in Chapter 3, where Zaha is shown to be wearing a "Alien" t-shirt as a reference to the Alien movie franchise. Later on in Chapter 11 he is shown wearing a shirt with a facehugger on the front, which is also a monster from the Alien franchise.

Personality
While equipped with murderous abilities and the intent to use them, Sanko is otherwise a friendly teenage boy who likes to eat spaghetti with meatballs stuffed into sandwiches, watching the TV show Alternate Dimension Death RUN (a spoof on anime or tokusatsu series) and generally enjoying life despite everyone wanting to kill him. He can be led astray by his happy-go-lucky attitude, and Avakian scolds him when this happens, though they are not so different. As Sanko points out, they both have no idea how to steer their spaceship, and Misetani Box is able to scam them both easily. Sanko likes to work with clay and makes clay figurines of his favorite characters. In school, he did his homework diligently, presenting his Photochtoncontainer with a spaghetti and meatballs sandwich, while other students brought them back broken or faulty. Sanko refers to himself as boku (僕), a personal pronoun used by boys and more soft-spoken men.

Being bullied and otherwise having to always hide his identity, for other people will try to kill him when they know who he is, left him lonely. When Shimada isn't interested in his bones he immediately latches on to him, despite how dangerous he is. In chapter 8, he tackles him with a hug when seeing her, making Shimada show a rare surprised expression. He also made a clay figurine of him. He has a familiar relationship with Avakian, who acts as his caretaker, like a parent or older sibling. He thinks of Moja as cute and helpful, frequently hugging the little robot and hosting a cooking show with him.

Zaha and Avakian infiltrated the Treegun Elementary School. Avakian then hacked the system and made Zaha a student there, since it's was a safe place for Zaha. As Avakian was finishing the registration, Zaha had to say his name, but since he was dying from hunger, he said Meatball Spagetti and was registered under that name.

Zaha woke up in the morning and headed to the school bus. Then in the classroom, the teacher asked them to see their homework using the Photochton Container. Zaha released his container to reveal a meatball and spaghetti sandwich, claiming to be his favorite.

As he was returning from school, Zaha came to a sealed section, trying to look through it, he saw someone and got scared. As Zaha explained what he saw, Avakian got suspicious it may be someone after Zaha, so he wanted to go and check it at night. Using Dark Flesh Avakian removed Zaha's Phylactery that makes him go to sleep at night and then they headed towards the sealed section. When they entered the sealed section, they saw kids and followed them to a corridor full of dead bodies. Then the person Zaha saw, appeared behind them and Zaha used his Dark Flesh axe to attack them, but that had no effect. He continued attacking them, but was easily repelled back. Realizing the person wasn't after Zaha's life, the person introduced themself as Shimada Death and that they came to feast on this ship. Shimada then revealed that the two "kids" Mini-Bucketmen, were the one who killed all the people. Immediately after that the Mini-Bucketmen attacked Zaha, breathing poison into Zaha's face. Being seriously affected by the poison, Zaha was barely standing. He then threw his axe at one of the Mini-Bucketmen killing him, but then as the other one was about to kill him, Shimada Death touched him and made him explode, claiming him to be their 200th to eat. Zaha was surprised that Shimada didn't want to kill him due to his bones, but Shimada told him they didn't want anything as they already had all and left. As this was the first person that he met that didn't want to kill him, Zaha considered becoming friends with Shimada.

Plot
Zaha was floating injured in space, when the Waste Mafia Ship The Kahiya took him in. While the ship captain was inspecting him, he saw Avakian and figured he was Zaha Sanko, so he decided to take everything from him. At that moment Zaha woke up and asked to leave his underwear. Later when Avakian woke up he went to Zaha and seeing him being frozen, he started a fire to warm him up. As Zaha woke up, he was freezing and he used his Dark Hide disguised as underwear to dress himself up. Not realizing the fire spread and caught Zaha on fire, as he was running around trying to put out the fire, he accidentally caught on fire part of the crew that gathered in front of the door of the room he was. The three-headed captain then tried shooting Zaha, but the bullets bounced off. Zaha then requested his Dark Flesh from Avakian, turned it into an axe, and proceeded to kill the captain. Striking the captain with the axe, removed all the skin and meat from him leaving only his bones and Zaha claimed he will be taking them. The rest of the crew tried to kill him too, but ended with same fate. Zaha and Avakian then took the ship and headed for their wanted location, a black hole. On their way there, Zaha found some weird bread and then used an ancient Photoleowave to bake it and then eat it. Reaching the black hole, they came out of the ship and jumped towards it.

As they went into the black hole, they saw a researcher who believed a world existed after the black hole. Zaha then explained him that indeed such a world exists and it's called Dark, but ordinary people can't reach it. Arriving on Dark, he started looking for Misetani Box. Upon finding her, he exchanged the bones he collected for a Dark Core to complete his ship and some Sakamanju. As they were eating the buns, they discussed what were they going to do and that Zaha wanted to contact Shimada, as their ship would be ready. On the way of the ship, they got attacked by more people wanting to take Zaha's bones, but he quickly dispatched them. Installing the Dark Core to their hidden ship on Dark, they now were able to freely travel on and off from Dark. Wondering how they would drive the ship, the new AI Moja came and revealed himself. Zaha then contacted Shimada to tell him about their completed ship.

Abilities

 * Dark Hide (闇の皮, Yami no kawa): A protective set of clothes that can transform and surround his entire body; it can repel all kinds of attacks including bullets, blunt impact and stabs.
 * Dark Flesh (闇の肉, Yami no niku): By combining a Dark Bone with the aforementioned Dark Flesh, Zaha can create an axe that upon hitting a living being removes all skin and meat from them, leaving only their bones.
 * Enhanced Strength: As a Dark native, Zaha is incredibly strong, even as a child, able to kick a highjacker ship off the excursion module and able to crush someones head with one hand.
 * Regeneration: Zaha mentions he can easily regenerate from most injuries, but this takes a lot of time and energy, making sustained damage able to incapacitate him.
 * Dark Vision: As a Dark native, Zaha can see normally even in total absence of light.

In chapter 9, Sanko has trouble reading difficult kanji on a sauce description, perhaps because his education was cut short. In chapter 7, he stated that he knows about 200 "star words" - which probably stand for kanji. For comparison, Japanese students have learned about 1000 kanji after finishing elementary school.
