Is my manga story good?

This boy lives alone in a house. He's a pretty laid-back kind of boy. He doesn't hate work just a lot of work. His name is Ziger, he's a pretty cooped up kid because he doesn't like being with friends. He doesn't see much interest in people really. He has never met his parents or has any knowledge of them except that they abandoned him. He has no friends but he has a hobby; fighting. He used to get beat around as a kid so he got stronger and is a better fighter than a regular boy (he's about 15. He doesn't have friends but he has an enemy: the rich and talented Tad. Who everybody loves and adores, who used to picks on Ziger to put him down. Anyways one fateful school day a ship comes flying buy and within it people with uniform. The people had an aura beyond anything this town has ever felt. They say they want Tad and ambush him right there on the spot. They murder Tad because he was the destined savior of their planet. Everybody was terrified then one of the people asked their leader (an old man) if they could kill some people. The old man nodded and the warrior attacked a child with a quick fist; indistinctively Ziger stopped his hand. Even though Liger does not care about people much he doesn't like people dying. Ziger pulls a staff out and attacks the warrior. The warrior fights back with an energy staff of his own. They duke it out and Ziger gets beat bad. THEN ZIGER GOES FOR ANOTHER HIT. While Ziger's staff is distracting the warriors staff, Ziger stabs him with a dagger in his back pocket. Then it becomes silent as everybody watches. Then the warriors laugh and ask him what is his name. He said "Ziger" They laugh even harder and the boy asks him them "what's so funny". You're the dumb animal predicted by fate that would attack us and die by us. While Ziger was confused one of the warriors stabbed him in the stomach. Then they just suddenly fled in their ship. It started raining and Ziger was left alone on the ground to die. He looked around and nobody was there. Not even the little kid he saved. He starts crying because he finally knew what it meant to be alone. And accepted the fact he was gonna die right there; as predestined by the warriors. But as he was about to die a beautiful woman talked to him in his dream. And said "Live live!" He replied saying "That there is no reason to live so why not just die?" The woman replied and said "I'm lilly and you just figured out your reason for living." Ziger said angrily, " Then what the hell is it?! To die again?!" She said, "No silly, to find your reason for living." "To find my reason for living?" Liger mumbled to himself. She said, "I'm lilly the angel and this one time I'm a let you go." Liger said, "What? What do you mean let me go?" Lilly replied, "I was commanded to take you to the afterlife but there's no reason to because it's not like you're that important to humanity anyways." He said, "So my life is so insignificant it doesn't matter if I die?" "Yes", she said. "There was nothing for you to live for. Nobody even stayed after your death, so I might as well pity you and let you live." she cheerfully added. (Long prologue short: He went back, cried, and decided to go venture out the world to see how to get to that world and find a purpose. Because that was his purpose and he would die for it. As soon as he leaves Tads older sister shows up and tells him he ain't leaving without her. Because she knew about those people and told him there were people 100x stronger than them out there. Ziger gasped. She said if you're going to leave take me with for revenge and so they went to venture out.) IM GOING TO ADD THE DETAILS LATER
