As the Lost City crumbled and was being swallowed whole by the ocean, the mist lifting once the monsoon came down, Harvard was running low on both options and means to cover himself. He'd use the remains of Atlantis to summon another monster, a spell being casted to take its soul and convert it to energy, as well as another spell to take the dormant remains, converting most of the mass of lands it once made into energy. He'd use this massive amount to set up two Fusions, removing Kyu and Nue to focus on Yata and Neko, fusing in two monsters into its system: Seimei and Genomix, the latter of which was used to take in the powers of Atlantis by the excess Harvard left behind. Yata's body would bore antlers and the mask of the doe-like beast, while Neko would take on talismans that coat around the monsters body. Harvard's fusionism, however, was not done, as he would try to set up one more seal, using the rainfall as its cost, as well as the aftermath of the two monsters, letting them fuse and transform into the ultimate beast.
Osiris.
"The amount of rainfall being made is probably enough to let it spam his final gambit over and over again, yeah? That means each and every one of those drops should have some amount of energy in it, even more than usual. I gotchu now, Sea Monster." He'd whisper to himself, not bothering to say such chants, his mind focused on conquering the beast that took to the air. A massive beam of light splits the clouds and forces the Umibozu to back away, letting it watch as something would crawl out of it: A Muscular beast in gold and bronze, the mask of Tutankhamun on its head, as well as having many hieroglyphs engraved in its body. Tales, such as the Book of the Dead and the Boat of Ra, were ingrained on its arms and legs, the names of the many Pharaohs that lived and died being on its back, its muscles shaped somewhat to resemble Ankhs. Because of the Fusionism, it granted more properties, from the lava-like hands from Atlantis, to having veins across his body akin to Genomix's antlers, to the winds that surround it from Yata and Neko simultaneously, to even inscriptions and kaiji that trails across the bandages in its body from Seimei. It was the ultimate creation worth weaponizing against, and it showed no mercy in leaping to the skies and firing a massive beam of light on all its sides, carving the clouds away, letting the sun finally return once more, if only for a moment.
The people finally gained back their needed sight against the harsh darkness and the heavy mist that wafted. As the boys tried to look up, however, they noticed that Harvard has disappeared. "Where did he go?" Zazel asked.
Solomon would piece together the answer once he saw his Parents float across the skies. "Zazel, get me up there." He'd demand. Zazel was about to question him, but one gesture from the Biblical Sorcerer lets the Demon know what exactly happened. He'd create Asmodeus to let him use as a weapon in case, having the sigil soar up high, letting Solomon hang on tight as he made his way to Osiris' hands. As he does this, Stolas would try to set up stars as he'd see the rainfall come down, shielding Khepros with its heat and light, a rainbow formed from such refractions, all to ensure it doesn't attack from above at the innocent people. As he did, he would notice that, as Osiris came down and watched the Umibozu rise up to try and land a hook, it would try to deflect it with just one of its hands. The other remains motionless, still. It doesn't try to raise itself up, nor does it attack back. As the Umibozu saw this and tried to take advantage, Osiris merely had to jump and aim an attack from the Sun God Ra, the hieroglyph ingrained into its body glowing, a beam of light that cuts down the water and boils it alive. No matter how many times the Umibozu attempts it, it can never reach that other hand. Solomon's assumptions were pretty simple upon seeing the brief scuffle.
That must be where Harvard is.
"Drifting Sea..."
"Harsh Wind..."
"Mountain Top..."
The boy's eyes widened as he heard those phrases, turning his head to the Sea Monk and seeing it hold its hands in a mountain pose. Osiris would see this and have the kanji begin to glow instead, spirits being casted out as a response. Such spirits would quickly swarm Solomon, spreading themselves evenly as a makeshift shield, their hands closing the vital parts of the barrier as the chant kept going.
"Magatama..."
"Raijin..."
"Fujin..."
"Yasaka!!"
The water droplets began to get charged up, the energy now being visible. A stark difference from its first instance, having Solomon hide behind Osiris to let it take as much damage as possible, sneaking through with its body in order to reach the hand and go inside, using Asmodeus to summon the Demon, and by extent, the Dragon, alongside releasing the spirits that acted as a barrier, letting them guard and seal up the crack, as well as provide some light to find Harvard.
"Water Magic....Susano'o...."
The rainfall was like blades against Osiris, yet even with such damages being done, cutting across his body and even breaching and breaking through one of its hands, the Pharaoh merely walked up to the Sea Monk, staring down at it as it approached. Even with such injuries, all it did was merely throw a knee, forcing it to reel in, before being struck at the back of its head with its mangled hand, utilizing the God Atum to regrow it as a more malleable source.
That was when a voice was being heard again, a hum once more. Someone was within its waters. Someone was trying to escape from the Umibozu itself.
