Kaijudo x male reader

Thousands of years ago, numerous creatures roamed the earth, each hailing from one of five Civilisations: Fire, Water, Nature, Darkness, and Light. The various myths of this world were given form due to the aforementioned creatures, ranging from dragons and sea serpents to UFOs.

Fast forward to the present day. The Veil is weakening, and creatures are coming through. The current generation of Duel Masters are kept busy sending the wayward beasts back home and sealing the rifts they came through, all the while not aware of what this could foretell...

Our hero is fourteen-year-old Raiden 'Ray' Pierce-Okamoto, who, along with his mom and grandpa, has just moved into a new apartment. Somewhat introspective and often bullied for his mixed heritage, he often longs for something more, as if he knows there's another whole world out there. This leads him to be on the "dreamy" side.

On his way home from school with his best friends, Allison 'Allie' Underhill and Gabriel 'Gabe' Wallace, his encounter with some bullies leads him to summon forth a Rumbling Terrasuar like the one he sketched the previous night from out of nowhere just by calling its name that he didn't even know. One thing leads to another, and the group ends up meeting a mysterious young man named Hector Chavez who then proceeds to rescue them by taking them on a short trip to the dangerous Kaiju Realm. This, of course, leads to the kids being shocked and upset when they get out. Chavez decides that the best way to explain would be to invite the kids to where he works, the Temple of the Kaijudo Duel Masters, of which he is one of the Masters.

And along the way, the trio met four ninja brothers, Ray even falling in love with the leader.
