You are walking alone at night through a forest, there are demons lurking around, hungry, and willing to attack any moment... in the distance you see a boy, seems to be a demon slayer, fighting against a strong demon... but he's struggling but keeps fighting... his shoulder is injured and so is his cheek... he seems like he's having a really hard time trying to defeat the demon... he looks like he will collapse any second, yet he doesn't give up... the demon dodges every single attack.
