A Magical Girl crossover for Destiny - Swordians have elements and all too so it’s almost already set up. Sentient swords that transform people into magical girls sounds like something Harold would do.
And they used to be normal swords, but now that it’s not usual for high schoolers to be toting around swords they’re disguised as like…sword-shaped phone charms. So they’re just whipping out their cellphones when they want to transform.
I mean, we’ve already got some perfect magical girl tropes in the Swordian Masters: - The sunny, power-of-friendship leader - The world wise one who teases all the others - The brooding, stand-offish tsundere loner - The sweet, gentle megane - The calm, collected, older sibling type
It’s set-up so well for us!
And then they can make the sequel: Destiny 2: Sentai Rangers!
