From birth to death, Alfin has never achieved anything in his meager life. His greatest accomplishments were made while playing Nirvana under the lead of his brother. He was nothing more than a side character on his brother's epic journey.
And while his sister had followers and fans due to her beauty. Alfin was always ignored or even hated in his brother's community long before he got kicked out.
To them, Gyatri already fulfilled most of the role in the party by being an excellent Externalist. And his sister was a unique existence who could control the void. While alfin was only an above-average mecha operator, they only reached his high rank under the constant support of his older brother.
If not for the pillar known as Gyatri. Alfin would have just been an average player in his last life who only played this game casually.
