Story:
Seizu was born in a parallel dimension named AlterWorld. After 140 years of training, he became very able in combat, which is extremely important in his dimension, and he got the ability to travel between worlds and dimensions by using portals. He's the prince of the third region of the AlterWorld

-Seizu is able to control his digestive process, as well as his breath and heartbeat
-He can create a portal on the end of his esophagus, sending his preys into the AlterWorld by eating them

About the AlterWorld:
The AlterWorld is an alternate dimension that humans can't reach in any way. It's completely separated from Earth, and only Seizu and his family are able to travel between these two worlds. AlterWorld is extremely different from Earth under many points of view. First of all, civilization is almost totally absent; the whole dimension is divided into four regions, each of them has their own kingdom of dragons. The four kingdoms are specialized respetively in combat, supply, tecnique and escape abilities.
In the AlterWorld, biomes alternate in a very abrupt way: 100 meters before you're freezing in a tundra, 100 meters later you're melting in a desert.
The main problems are the creatures that inhabit the AlterWorld. They're all scary, extremely dangerous monsters that kill each other continuously. The smallest creature in the whole AlterWorld is as big as a lion, the biggest one is 5 times the size of a whale; plus, the creatures that inhabit AlterWorld are ALL carnivorous. Here's some examples of creatures:

-Cyros: A Pterodactyl-like monster with 150 sharp teeth, a spiked club on the tail, short horns and a tough armor; wingspan is 10 meters

-Bikoris: An huge lizard, armed with a crest of sharp spikes on its back, and a lot of small spikes all along its tail. Their claws are nearly always dirty with blood, and they can reach a size of 15 meters. If a Bikoris devours a creature, it obtains that creature's powers

-Korpos: They're mosquito-like creatures with two schytes beside the mouth, which is similar to a skark's one. They grab the victim and take them into the air to suck 80% of their blood, then they drop the corpse. They're also able to turn the blood they ate into acid and spit it against enemies; maximum size is 7 meters

-Kretoxin: A marine monster, similar to a shark, with a long hollow horn; it uses the horn to stab its victims and wait for them to bleed to death before devouring them. The suffix "toxin" is due to its horn being full of poison, which can be injected into the victim, causing the rapid decomposition of vital organs. Kretoxins reach 10 meters, and they're considered the less dangerous marine monster
