A giant Yo-kai born from humanity's conflicts and feelings of discord. He rips his enemies to shreds, with his strong sorcery, sharp claws, and spirit power. This is the true form of Noruka and Soruka, but, once they fuse, they can no longer turn back into two people.

In the game, Noruka and Soruka make their debut, appearing before Jibanyan, Komasan, and USApyon. They tell them that they didn't have enough jewels to grant their wish, and that they so happened possess the last two. Due to possessing too much power, Noruka and Soruka were sealed into the book "Yo-kai Sangokushi", which was created by King Enma. They could not escape from the book, but as a long time passed, the seal's power weakened. Their magic energy leaked out of the book, causing people in the outside world to act weirdly. With nothing restraining the two, they wanted to gather the jewels and wish to exit to the outside world. Noruka and Soruka thusly challenged Jibanyan, Komasan, and USApyon to an all-or-nothing battle for the jewels.
After being individually beat, Noruka and Soruka resorted to fusing together into the monstrous being Norukasoruka. Despite knowing that they cannot return back to their two original forms, they could not risk losing and staying forever in the book's world. Then started the final all-or-nothing battle between Norukasoruka and the three heroes. He's ultimately defeated in battle and never heard from again.
Norukasoruka is a big enemy unit that takes about 4 panels of space, so like most bosses in Sangokushi combo attacks are not possible against him, he moves about 3-4 panels at a time, he doesn't have ranged attacks but he can damage multiple targets, so its recommended to keep all units far from each other, his registered attacks are:
A frontal neutral element attack with a 3x3 grid range.
A frontal physical attack with a 3x3 grid range, has a chance of lowering the stats of the targeted units.
A frontal magic attack that absorbs stats from targeted units, 3x2 grid range, doesn't inflict damage.
His soultimate move, which targets everything withing 4-5 grids of distance, this attack can inflict about 100-300 points of damage.
Norukasoruka is based on the Chinese concept of the yin-yang (Japanese: 陰陽yīnyáng, "dark—bright") this philosophy describes how opposite or contrary forces are actually complementary, interconnected, and interdependent in the natural world, and how they give rise to each other as they interrelate to one another. Many tangible dualities (such as light and dark, fire and water, expanding and contracting) are thought of as physical manifestations of the duality symbolized by yin and yang.
Norukasoruka's name comes from the phrase "win or lose" (Japanese: 伸るか反るかNorukasoruka).
He is the second Boss Yo-kai fusion to appear in a spin-off game, with the first one being Dai-Yoma Nura-Neira.
