Everlasting Shine by TOMORROW X TOGETHER

The intro starts with Irene is sitting next to a tree sleeping. She then wakes up.

We'll try again, try again

Till we overcome what it is that holds us here

Try again, try again

Till we find the hope lying somewhere within

Irene covers her face as the sunlight blocks her, before she smiles at it. Her hair begins to glow whitish gold and so does her eyes, with generating an ivory gold aura.

Our tears move on, our days are all so colorful

Unleash your light forever

You'll shine like a diamond

Union Academy is then shown, with different flags of the countries, including United States, Japan, Germany, France, Italy, Russia, and more, with the Kandorian flag in the middle. Irene then holds up her sword.

Virtuous Irene

I just can't separate angels from demons

The background shows Irene falling into a black abyss, as she is suddenly surrounded by a glowing aura.

This world is filled with contradictions

It ain't what I expected

Irene is shown once more in a dark background, before the background turns bright and sees her friends, including Ruby, Ichigo, Shirou, Ryuko, Izuku, Asia, and Naofumi all smiling and laughing behind her.

Anything I gave up for that cause wasn't worth it

Lumine is then shown to be holding a book, and Ritsuka is shown walking as his Servants follow him behind, as he forms a determined expression, before the background turns to show many villains including League of Villains, Salem's Inner Circle, Khaos Brigade, Sternritter, and others are shown, alongside bullies and corrupt professors surrounded by dark auras.

We'll try again, try again

Till we overcome what it is that holds us here

Our tears will move on, our days are all so colorful

Unleash your light forever

You'll shine like a diamond

Irene as a baby is shown embraced by her parents, before the scene shifts to her running before she flies toward the sky, leaving behind a trail of gold and white light.

You'll shine like a diamond

Irene is then shown standing in the grassy field, now with her old and new friends, as her necklace is lying next to the tree.
