The Drunkard's Brother

What would life in the guild of FairyTail be like if Gildarts had another kid that he didn't know about right under his nose? What if Cana had an older sibling who was there to make her feel safe and protected as she felt abandoned by their father?
From the young age of 4 to the grown age of 13, Keikuma knew that his mother did not want him around, but stuck around to be able to take care of her when she would get into her drunken stupors, Just before his 13th birthday, his mother died of alcohol poisoning, leading him to no longer feel her had a purpose and went ahead to the nearest village to see who he could help instead to give him the feeling of purpose in life. Hearing the rumors of guilds helping people who would pay them to come to them, the young teen asked the nearest adult who the most popular guild was, who responded with Fairytail.
Watch as this kid goes through the ups and downs of guild life while accidentally making people left and right fall for him as he subconsciously flirts with everyone. See how he learns more than one magic skill and learns the value of life for himself and sees how others value him more than his mother had ever.
