DISCLAMER: The script for the movie is not mine. I copied and pasted it from idea wiki, and then put it on here. That way you could read the script more easier.
PLOT: A Robloxian named Jake (Oscar Isaac) is a citizen who has no friends and always been alone, and people like to make fun of him. Until when 1x1x1x1 (Mark Wahlberg) starts attacking Planet Builder, Jake teams up with ROBLOXians Melvin (Chris Evans), Jesse (Jessica Chastain), Omar (Ed Helms), Chad (Mark Ruffalo), Builderman (Ben Affleck), Donny (Steve Carell) (who later betrayed the gang), TheDiamondMinecart (Daniel Middleton), and must go on top of their universe to find Builderman (Ben Affleck) to help and save Planet Builder from 1x1x1x1 from trying to destroy the planet.
Waking up in the body of a Romani Archiman is acceptable. Getting 3rd and 1st True Magics is nice. Getting Beasts as pets - delightful. The world of DxD is unforgivable. It's a world where some teenagers who aren't even two decades old somehow mystically defeat the descendants of legendary heroes, ancient demons, powerful dragons, etc. Why does this happen? Simply because! Simply put, this world only makes sense because it doesn't. And now, I have to put up with the fact that I live here. Such pain. (DxDxMulti)
