1990, and Tatsumi Mondo Hakase disappears, leaving his wife to raise their five children on her own. 1992, and Mrs. Tatsumi goes to search for her husband. She makes her children PROMISE to watch out for each other, and her daughter gives her a charm, a ringing protective bell. And the airplane she boards crashes, or explodes. Her body is never found. 1999 to 2000.... Matoi was 24 years old. He was born on January 21, 1975. He worked for the Special Rescue Brigade, of the something-something Fire Department. As the eldest brother in a family of five, it fell to him to take care of the others when they lost both their parents. This only lasted until they were old enough to move, and move they did! But when the circumstances of becoming Gogofive forced them to live together in the same home, he drove his siblings up the wall. He would walk in on his sister in the bathroom, accidently break something and just shrug and say "You can fix it," to whoever's thing he had broken. He rose to the challenge of being the leader of the group admirably, and drove the others to more exercise and dicipline than they would ever have done left to their own. He loved them all dearly, and would like to have protected them and not had them battle if he could, but that was not a choice. He had been somewhere between a father and an older brother when he had to take care of them, and it was a hard role to adapt away from. He had a great deal of pride and would rise to almost any challenge. Once when his complaining about their lunch drove his siblings to challenge him to make his own, he went out and tried to make curry, only to learn from a tiny girl that he really had no idea how GOOD curry should be made! He handled that all right, and they became friends. He had a friend, a senior to him, whom he competed with and who was quite capable of rescuing him when it had to be done. Eventually he just accepted that he and his friend both had incredible strengths, and matched each other. Himself, he was very courageous. The only challenge he ever wanted to run from was when his father arranged a potential-marriage meeting. And he discovered the girl was just as competitive as he was. He liked her, though. Perhaps something will come of it after the Saima are defeated.
