- Description from 69shu

Harry Morton was born in an age where magic and mana ruled everything.

He was unable to awaken his affinity and to make things worse he was born with a broken mana core foundation which meant he would never be able to create or develop a mana core. Since he couldn’t create a mana core, he would never be able to draw mana—not even the slightest strand.

He was the first person to be born without a mana core foundation, the only one with the inability to draw mana. Due to this, he was regarded as trash by everyone: his parents, his friends, the society and even the academy he attended.

It was until one day, during a mana beast attack when he almost lost his life.

He saw a strange white line rapidly moving downwards, towards him. Unbeknownst to him, the white streak went into his body.

When he woke up the next day, a strange message appeared in front of him.

DING!!
