Backstory
The main protagonist of this story, Jio is a boy with great battle skill, great trust towards his friends and an ability to persevere, but he also has an obsession with money and is not soon to show his feelings, often hiding them or blaming other factors.
His dream is world domination, which other people often laugh at, calling it a child's dream until they see his abilities.
Jio started his life without friends, the people in his village forcing him to leave after the death of his only friend Jin's parents for which he was blamed. He was later trained in the wild by a wolf, known as Zero. However, after completing his training he was chased away again, giving him a chance to complete his dream.
His third friend, came in the form of Ruby Crescent, a girl in search of her father. At first, he helps her as a paid bodyguard, but leaves once she runs out of money. She ends up fighting a man claiming to be Satan, but the real Satan (sealed inside of Jio) easily beats him once Jio is knocked out. Once Jio is conscious again, he says he will follow her until she can pay him for saving her. He claims (in front of her) that he is only her bodyguard and nothing more, but Jio sees Ruby as a precious friend and even seems to have a crush on her.
Bio For Natsu (Fairy Tail)
Natsu Dragonil (ナツ ドラグニル Natsu Doraguniru) is the main male character of the series and is a member of the Fairy Tail guild. His name, Natsu (夏) means "summer" in Japanese. His member's stamp is on his right shoulder.
Natsu has a carefree and reckless nature and constantly friendly bickers with other members of the guild. He has a particularly close, and competitive, relationships with fellow members, Gray Fullbuster and Erza Scarlet. He suffers from motion sickness from all modes of transportation, including trains, boats, carriages, mobile guild halls, and even people carrying him on their back. Along with his partner, Happy, a magical cat, he is first introduced in the manga as searching for his missing foster father.
His rose colored hair, scale-skin scarf and fire magic earned him the nickname "Salamander", one which he shares with his foster father, Igneel. His strength and reputation as one of the strongest fire mages has made him one of the more prominent members of Fairy Tail. Erza states that Natsu's true power is in a slumber state and has yet to awaken. With self-belief, Natsu will one day become stronger than Erza. It has been shown that Natsu's power exponentially increases in conjunction with his emotions, evident from his fight with Eligor.
It is unknown what became of Natsu's biological parents. Igneel, the fire dragon, discovered Natsu in the forest and raised Natsu as his own child, teaching Natsu how to write, speak and the powerful magic style, Dragon Slayer, a style said to be developed to intercept dragons. He has the ability to eat all types of fire, with the exception of his own. Natsu learns from Zarti that his magic is considered "Lost Magic" due to its destructive force. Igneel's reasons for teaching this magic style is unknown. However, at a young age on July 7 in year 777, seven years prior to the main story line, Igneel disappeared, leading Natsu to arrive at Fairy Tail. Thus far he has only met one other Dragon Slayer user who, like him, learned it from a dragon.
Despite his reckless nature, Natsu shows great wit in battle, quickly identifying his opponents' weaknesses, and forming strategies to block the plans of his enemies. His dedication to his teammates and his guild is strong, preventing the deaths and self-sacrifices of several members, including Macau and Gray.
Natsu and Gray have constant fights, ranging from pillow fights to magic ones. Natsu also seems to be a sore loser, never admitting defeat. Whenever Gray and him have trouble deciding who won, they call on Lucy, who is for the most part, able to calm them down.
