Futaba Kudou is sick and tired of his family; as the youngest of his siblings he's considered the baby of the group and is constantly hounded over his cell phone. Things change one day when a girl suddenly falls out of the sky. Her name is Kiara, and she's an Amaranthine - a special plant that blooms in the land of the fairies and is rumored to have the power to grant wishes. Her magical abilities can only manifest once she is joined with her master, and she believes Futaba to be that person! However, as it turns out Futaba is not Kiara's master; and after a brief battle with an evil sorcerer that's after Kiara's powers, Futaba finds himself transported into a magical world filled with wonder. Together, the two agree to travel together to find Kiara's real master, making new friends along the way such as Bel-Bel the bunny wizard and Virid the prince. Can they find Kiara's master, or will the monsters and demons out for Kiara find them first?
Following its destruction many years ago, the world now consists of many disconnected lands that once again face the threat of annihilation. Sora is a young boy who lives on a tropical island with his friends Riku and Kairi. However the night before the trio is due to set sail on an exploration voyage, they encounter monsters known as the Heartless. During his struggle with them, a large Keyblade appears before Sora and he is transported to the faraway Traverse City. There he meets Donald and Goofy, two representatives of the king who are in need of his power as keybearer. Now, Sora travels with his new companions in order to find the keyhole hidden in each world and lock away its heart to protect it from harm, hopefully finding out what happened to his friends along the way. But with other evil forces afoot, will Sora and the others really be able to save everyone and keep all worlds safe?
Both MAR and Beyond the Beyond are about a boy who gets transported to another world through a portal made by someone from that world. And when they arrive, both meet companions who are taken with them, as well as one that treats them like a servant (Babbo/BelBel).
Unfortunately, Beyond the Beyond is much shorter and slightly less action-packed, but chances are, if you like one, you'll like the other!
