Alright, that scene in SRW30 was one of the most hype things in this game.
Playing the late game heroic music as a Magic knight Rayearth villain thinks theyve won by invading the party's home base, then the Sakura Wars characters and Gridmans allies jump in to save the Rayearth protagonist with their on foot fighting skills. While Lelouch walks into the room with his smug face and just goes "You lost this one."
They just put the IP's i'm actually a fan of in this exchange and it was exciting.
And now i know i'm reaching the last parts of this game specifically because they play the hero music, which in these sorts of games only start coming on in the late game, soon enough i'll be done. lol
