Back to the Demon King's Childhood [Western Fantasy]

[On hold]

[Past/present, dual timelines]

Thirty years ago, when Helun was ten, he was tested and found to have no talent for black magic, becoming the only useless one among the descendants of demons.

Seven years ago, when Alvis was ten, he was tested and found to have no talent for white magic, becoming the only useless one among the descendants of angels.

Today, thirty years later, Helun, the Demon King and leader of the demon corps, is just one step away from ruling the world.

Today, seven years later, Alvis comprehends time magic and returns to the past, thirty years earlier, to stop the Demon King from rising to power.

Seventeen-year-old Alvis tries to abduct ten-year-old Helun: "You're actually a little angel, baby~"

Innocent little Helun: "?"

Grown-up Helun, with new memories: "??"

Alvis, who only discovers after returning to the future that Helun's memories aren't affected: "???"

Every day when the Demon King opens his eyes, the first three things he has to do are:

1. Sort through the month's worth of memories that just appeared.

2. Keep his past self's feelings for Alvis in those memories under control.

3. Vow that he will absolutely kill Alvis.

Past timeline: raising a child, redemption, comeback and face-slapping.

Future timeline: sworn enemies, powerful but tragic, loving and fighting each other.

Past timeline: Alvis says, "Long hair looks good."

Future timeline: The Demon King wakes up to find his short hair has grown long x_mouth_eyes_mouth

4. Past to future: time passes at a ratio of 30 to 1.

Theme: The future is ever-changing, but the original resolve remains firm
