Nia Teppelin

There's no such thing as impossible. Because I believe in Simon.

📍 Her absolute faith in Simon expressed directly — the series' central theme that spiral power runs on belief, stated at its purest.

Even if I disappear, I'll remain inside Simon's heart.

📍 Her farewell just before she is taken by the Anti-Spiral — consistently cited as the series' most heartbreaking moment.

First Meeting in a Junkyard

Found discarded on the surface, Nia belonged to neither Lordgenome's world nor the humans underground. Her first meeting with Simon is a crossing of pure innocence and a boy's buried yearning.

Transformed into a Messenger

Her body is converted into the Anti-Spiral's instrument. Watching her fight the team she loved — with her self gone — is the peak of her tragedy.

Disappearing After the Wedding

After the Anti-Spiral's defeat, Nia loses her reason for existing and fades away. Disappearing immediately after their wedding is the series' most debated scene — and its emotional apex.
