Shade: 

Here we go, on a quest

'Cause we know we always try our best.

With friendship like we always knew

Rein:

If your main units are trash

Say the word I'll be there in a flash

You know I dedicate my life to you

Both: 

Oh, we will fight alongside our family and friends 

On this bloody battlefield 

(Shade): I'll plan the attack

(Rein): I'll drive them back

Oh yeah!

(Shade): It's time to fight for all our friends!

(Rein): Fight until the end!

Fight for those depending on us all!

And if the tempest starts to swirl 

Don't fear, don't shed a tear, 'cause

(Shade): I'll be your summon girl. I position our friends!

(Rein): I slay our worst foes!

Together we make a fearsome team!

So let's enjoy the time we have

Having fun at what we're good at!

We're playing a game

Yeah, you know the name, oh!

Oh! Fire Emblem Heroes

It's time to fight for all our friends

Fight until the end

Fight for those depending on us all

And if you find you're short on joy 

(Rein): Don't fret, just don't forget thatI'll be your magic boy

(Lucius and Lachesis) No matter if you use a staff 

(Lon'qu and Seliph) A sword, 

(Anthony, Berkut and Lukas): a lance,

 (Hector): an axe 

(Matthew): A dagger 

(Boey, Rein and Julia): or a magic tome

 All:

You know that we're all heroes here 

Doesn't matter low or high tier 

When we're put to the test

 We'll all do our best 

Oh! Fire Emblem Heroes

 Heroes

Meanwhile, Tiki and Leon are offstage sobbing because it was beautiful but the song left them out at the same time
