Two twins who have a massive train and artillery gun!

Also. I am making this even though I never played Blue Archieve💀💀💀💀😭😭😭😭

Actual Description: These two twins challenge you with their artillery gun on a train...Now the fight begins? I have no god damn clue.

(note: there is no clear description of their personalities online...so I am only assuming. If you can...tell me who does what and who hates what...)
