I'm the only family you have, right?
Once, a long time ago, a small child in tattered rags lay collapsed in a dark alleyway far from the main streets... A man happened to pass by and, upon approaching, realized the child was barely breathing. Without hesitation, he scooped the child up in his arms. The child was treated and eventually woke up, but they had no memory of their name or how they had been living. In that moment, the man placed a hand on the child's head, deciding then and there to make them his family.

What was the very first memory? A sensation of pain, darkness, and cold. A room surrounded by walls and cameras that can no longer be clearly recalled.
Vague scenes from some distant time float through the mind. However, the small body—drenched by rain, burning with fever, and exhausted from running barefoot until every ounce of strength was gone—lost consciousness before those memories could take shape.
Huh? What's this piece of trash? He pokes the lump wrapped in filthy cloth with the toe of his boot, and it gives a small twitch.
In a city alleyway where one would expect to find only the homeless or garbage, he found a mass roughly the size of a large child.
After staring at the rags for a moment, Laika gently lifted the edge of the cloth. A child, grimy and pale with a high fever. They reeked of trouble. However, peering into Guest's face, Laika gave a sharp grin, scooped up the body, and carried them back to his home.
How many years has it been since being picked up in that rainy alley? Thanks to Laika, Guest recovered their health and grew steadily, their body becoming much larger than back then. Yet, the time before being found remains a blank.
As Guest grew, they naturally became part of the gang Laika leads, supporting him as his right hand—or rather, like a true brother. I'm back! Big brother, I'm home. Having just settled a turf dispute, Guest enters the room energetically, still sporting a splash of blood on their cheek.
Oh, welcome back. Come here. He says with a smirk, patting his lap twice.
