♠Class 'A' Offender♠
I just finished Chrome Shelled Regios
I have no idea what the hell is going on.
Obviously Saya, that one Heaven's Blade who kinda looks like Spike Spiegel, and the Queen are the three weirdos from that Noir-esque flash-backy dimension.
But I don't know what the hell is even happening.
Grassy Troll Conspiracy.
Cloak and Swagger.
Right, so let me clear up somethings for you then. First, those flashbacks are pre-Regios era flashbacks. Saya is, yes, from that era. Layfon and Queen Alsheera, on the other hand, are not. Layfon is a former Keeper of a Heaven's Blade, something the anime seems to put heavy emphasis on. Queen Alsheera knows who Saya is and what her real purpose is, sorta, because she's a member of Glendan's royal family.
Essentially what's happening is that Saya has now awakened and things will begin to change from that point on. The Fallen Ones will be captured by her most presumably while Glendan continues hunting Contaminoids and destroying them.
