MTL - Demon Slayer Starts From the Proficiency Panel - Chapter 207 [207] Trinity

When I cleared the final chapter of a game that was a national failure, I became an unnamed side character in it.

A non-standard, unmeasurable, EX rank supporting character.

The daughter of a duke, the stuttering Maximilian, married a knight of lowly status at her father’s coercion.

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.

Her sister steal her lover

She thought it was a dream

after rolling and waking

Nightmare Reality

Her loved ones, her love, her life

They were all trapped in that big fire

burned to ashes
