Anime Like Marriage of God & Soul Godannar!!
The aliens interrupt your wedding day, so you pilot a giant robot together because that's what you do when you love someone. Godannar doesn't separate the romance from the action, it runs them through the same engine, so every fight is also a fight to protect what you just promised to protect forever. The show means it when it says the couple is stronger merged than apart.
SYNOPSIS
Goh and Anna are getting married. That's the plan, anyway, until alien invaders crash the reception and force Goh back into his mecha cockpit to defend Earth. While he's fighting for his life against the Mimesis threat, Anna discovers a secret weapon hidden beneath the city: a cutting-edge robot called Neo-Okusaer. With no time to think, she pilots it herself, rocketing into battle to protect the man she just swore to love. The moment their machines connect, something extraordinary happens. Dannar and Neo-Okusaer merge into a single, unstoppable robot warrior: Godannar. Now newlyweds Goh and Anna fight side by side from inside their combined giant robot, their marriage tested immediately by alien attacks, military politics, and the constant threat of invasion. This is part romance, part comedy, and entirely ridiculous in the best way. It's a show that knows exactly what it is: a love story wrapped in mecha action, where the couple's bond literally powers their giant robot. Expect explosions, heartfelt moments, and the kind of absurd charm that comes from taking a genuinely sweet premise and cranking everything up to eleven.
