An Intruder in the Start Tower AIIST

Taeyang, an outsider orphan boy from the Solar Zone, who never met his parents or knew anything about them, grew up in the Doom Orphanage after the mysterious owner of the place, Marie, saved him from the streets. In the orphanage, he met Dawgreen, a boy who became his brother and best friend.

After the orphanage got attacked by a mysterious group of people, almost everyone got killed, except for him, Dawgreen, and Marie, and he only survived because Marie locked him in the kitchen cabinet so the bandits wouldn't find him, but Dawgreen who was all this time with Marie got kidnapped by them with her, and Taeyang never saw both of them again.

When a couple found him a week after that, he was weak and still locked in the cabinet, then they saved him and took him with them to the Lunar Zone, the second zone outside the tower.

Years passed and Taeyang never forgot the creepy smile on Marie's face when the strangers kidnapped her and his brother as if she was truly happy with that, and when he discovered that the culprit of that accident was high ranking people of the Star Tower, he grew thirsty for revenge on those who took everything from him.

Determined to infiltrate the Star Tower, in order to be reunited with Marie and Dawgreen, even if it costs him his life, even hearing how dangerous it was for an outsider like him to infiltrate the divine tower, he didn't care and did his best to find those who were the light in his darkness.

But he had no idea what really awaited him as soon as he started climbing the dangerous tower.
