Detective Haika

You don't know anything about this? Seriously, where do you live? In a forest? This is very well known. Also known as SAO. A story about gamers who got stuck in the game and are forced to win the game or die. The main character name's Kirigaya Kazuto, or you could say Kirito for his username. And his friends are Asuna, Silica, Liz, and etc. Kirito used to play as solo player than guild, because he traumatized by being in a guild which all the members except Kirito, died and Kirito couldn't save them, including Sachi. As the floor of hard bosses go on, Kirito is forced to join a guild.

Later, Asuna and Kirito become a couple, and they decide to retire from the battle front for days. During that, they found a kid in the forest. Her name's Yui. She later found out to be another data in the game. Yui become Asuna and Kirito's daughter by calling them father and mother unofficially. Silica is a pet tamer, whom Kirito helped, and Liz is a sword maker, whom Kirito asked to make his sword.

After Kirito beat Sword Art Online game, he logged out from the game, but Asuna's not. She's transferred to a game called Alfheim Online, ALO for short. Thus, Kirito enter that game again along with his sister, Suguha, to bring Asuna back. It have a good romance and action story. And NO. I'm not telling anything about 16,5. The more modern of online game after this is Accel World.

So, even if I die, you keep living, okay? Live to see the end of this world, and see why it was born... The reason why a weak girl like me ended up here... And the reason you and I met.
