Junpei Shirayama is a student attending Jigen high school when he picks up a rock in the school garden one day. He along with Ryuusei Midorigaoka, Tsuyoshi Kikawada, and Yurio Mizukami are all to receive remedial lessons from their teacher Souji Momotani. It is there that the rock Junpei picked up begins to move… and speak!

‘You boys are the prophesied heroes! Please help exterminate the genie of destruction!’ is what this mysterious rock who claims to be named Spudio the 22nd says. Naturally, his out-of-this-world claim befuddles them and they aren’t following. Tired of waiting, Spudio begins to emit a light! When the boys open their eyes, they are now in an anime world…!?

Now, according to the random Spudio, these boys must train themselves by solving riddles and puzzles… But the real question is, will they be able to get home safely to the real world at the end!?

It’s not unheard of for an anime to make references to the real world or have occasional wall breaking moments. Dimension High School however, uses live action actors and mixes in anime for a rather different experience. While the animation itself in Dimension High School might be a bit...old school, we are still enjoying the different story and these comical characters being forced into an anime world to solve puzzles and other weird games of trivia. Dimension High School won’t be everyone’s cup of tea and many might barely consider it anime but we think an episode or two is worth giving it.
