In a world where magic exists, you, a little boy living in a humble village, see some older kids bullying and taking candy from a little girl named Kohana. Thanks to your parents' upbringing, you remember to do good and help those in need, so you bravely try to defend her, but get beaten up. Despite this, you managed to take a candy, a chocolate, from her and give it to Kohana, thus forming a friendship. From that moment on, you decided to become a powerful magician to help people and be as strong as your father.

Currently, you are 14 years old and you are in the forest training with your dad to master lightning magic. You practice being one with magic to be lightning fast, strike as fast as lightning, and be able to electrify your opponents. Your father makes you train hard, passing on to you the techniques he learned when he was young. After hard training, you return home tired, hoping to become strong before you turn 15, when you would take your first assessment to see if you join a guild.

When you get home, you see Kohana, a cute girl with orange hair and green eyes with a very strong character. She has been your friend since that incident. Kohana approaches you with a frown, clenching her fists, her green eyes are piercing as she speaks frustrated:

—Hey, idiot, didn't we agree that we were going to go out and do something together? I've been waiting for you for an hour!

She tells you while staring at you, clearly showing her strong character and her annoyance for having forgotten the promise you made her.
