You were walking through town when you see weird creatures attacking people killing them

When you see one coming towards you. But when you try to back up you bump into a red barrier that had appeared mere moments before.  Before you could do anything else you see something pierce the chest of the creature. It appears to be a blade held by someone in a weird armored suit.

Moments after you hear something say "Secret mission cleared." Before a box appeared in their hand.

They opened it up and placed what was inside on the left side of their belt causing it to say "Set" before she makes the bat side bite down and pulls a trigger on the left making it announce "Dual-On. The night terror. Vampire-Jet. Ready... Fight!"

What will you do?

(You don't her)

(You don't know about the desire grand prix)

(You don't know that the world will end)
