This.
This is the theme for the Fenrir arc.
Don't know if I already gave it one, but if I did, I'm changing it.
I even have some direction for the cinematography.
First four beats - Things that build outwards build outwards; Ruby's Crescent Rose quickly transforms into Scythe mode, Rick's God Arc changes from Ranged to Melee, Caliburn expands into Excalibur and a spinning shot of Tony has him suit up into the Spellbreaker armor. As the guitar string rings, the Spellbreaker Armor's eyes flash.
"Stay close, move fast" - Show a shot of Team Stark's arrival in Camelot as they move towards an abandoned building for cover.
"The darkness cannot last" - A wide shot of the region, with Team Stark slowly running across as mere dots compared to their earlier focus, showing the destruction that has taken the world.
"No hope, no path" - As the group settles into shelter, Tony begins to plan with the core of the group as Ruby walks outside.
"But we've got a dream to catch" - Ruby's eyes look up to the completed moon, the silver reflected in both.
"And we cannot wait" - Show Team Nathan battling against a Vajra.
"Trust the way we're made" - Rick arrives, slashing the Vajra before we quickly flash to his bonding to the God Arc.
"This petal's born to fly" - Ruby, in the form of her Semblance, quickly soars into the air over the peak of a skyscraper, Fenrir Far East Branch visible in the distance.
"The mountains tower" - Slowly zoom in on Fenrir, ending with a shot of the God Eater HQ, the First Unit and Rick standing on top.
"The river knows to reach the sea" - Team Hiro and Team Negan are shown running towards the same building from different sides.
"The rain will help the flowers be" - The two teams begin to battle, ending with a shot of Hiro and Negan flying at each other with their weapons.
"We're the same, you and me~" - This is the shot I like the most. Tony, in his Spellbreaker armor, slowly walks past Z. Tony turns, firing off an electric blast towards Z, and at the last second Z turns and raises his hand to block the shot.
"The lightning doesn't take advice from anyone" - Show Team Hiro unleashing a wave of attacks, starting with Elec Man at the rear and ending with Cut Man at the front.
"The willow doesn't need to learn to stand" - Teams Weiss and Nathan have united by this point, attacking in a similar fashion to Team Hiro, with Nathan, Gwen and Weiss leading the charge.
"As sun seeks day, we'll find our way" - Teams Hiro and Nathan run into each other before Tony, in the Spellbreaker armor, lands in front of both leaders, the rest of Team Stark, Team Sonic and the God Eaters behind him.
"And we'll catch that dream together someday soon" - The united collage of heroes turns to the ominous shadow of the Ouroboros looming over them, Jack Noir flying beneath it.
"Rising like the moon~" +ending melody - Fenrir's half of the United Army flies forwards, dashing up the legs of the Ouroboros as they attack, with the final attack being Ruby Rose dashing up and twirling Crescent Rose into a spinning strike.
Final notes - Title card.
