Vanguard! My Guardian That Watches Over

Someone who watches from afar.

Someone who is by their side.

Someone who will protect their most special moments.

They are their when they need them the most.

Almost like...their Guardian.

The story of Aichi and his friends going through many challenges and bonding with their cards as they fight against the forces of evil that threatens Cray is one of the most legendary tales.
But what if those tales were told differently?

What if there was one person who changed their lives but also guided them to their destiny.

More than they can ever imagine.

But they're not the only ones. Along with them is their guardian who will soon discover her role and purpose in their lives.
