The sniper didn't shoot Makoto. When Keigo was hugging him, one of the monster mascot (the little one) kicked a stone and it hit the little brother.
Here the monster mascot looks at the stone -

...and here is when the monster kicks it and the boy gets hit in the head

It's more like the "monster mascot was testing something out or knows something about the brothers. Its the same mascot that lured Makoto and attacked him in the first chapter.
The story has got me at the edge of my seat.... can't wait for the upcoming chapters!
I don't care if the kid is really dead, has been dead for several chapters, or has regenerative powers ... Sniper-chick should have obeyed orders and NOT interfered with the brothers.
Even if the kid has been a mascot ever since his encounter with the elephant mascot, I still kinda wish that the sniper didn't shoot it. There was potential for the story to take a different arc...I guess?
Now I just wish the little brother is actually the little brother, and he has regenerative powers
