Neither of the twins knew how strong Sun and Moon Obliteration would be at this point in time. The last time they used it, they weren't even in the Transition Realm, after all.
Sun and Moon Obliteration basically used the twins' Light and Dark Elements, clashing them against each other. Usually, Rean and Roan's Dark and Light Elements worked together and complemented one another. However, even though that was the case, they were two opposite elements. In this specific attack, Rean and Roan allowed them to go berserk, forming a devastating power.
With that, Rean and Roan spaced themselves from each other as they brought their weapons out. They both raised their weapons high, gathering Dark and Light Elements as much as possible. Their weapons, of course, helped with that stage a lot.
'Death Style!'
The problem was the conditions to use this attack. Charging the Dark and Light Elements, launching an attack against each other, making sure that each side had the same amount of power... all of that while making sure that the enemy was located in the middle of the clash. It was simply unusable during the heat of battle. It was basically a type of attack to use against enormous and slower enemies, which was the case the last time the twins used it.
As the two weapons shone with Dark and Light Elements, Sword and Scythe Intent began to resonate from them. Both weapons turned ethereal as any similar weapon to their own began to tremble in excitement. The third stage of weapon intent, Call of the Weapons!
'Seventh Form!'
Normally, it wouldn't work against enemies at the Void Tempering Realm and above who had their own Pocket Dimensional Realms. Those enemies would be able to tell that a breach in space was present in that location and that a Dimensional realm was there. Instead, the twins' dimensional realm would be open for attacks as the entrance that's usually located in the beings themselves was completely exposed.
However, they found themselves in the perfect situation at the moment. They could do the initial charge while still in the Soul Gem Dimensional Realm. Then, they waited for the moment the demons passed by the area where they could exit the Soul Gem Dimensional Realm. They could do that while the demons outside would be none the wiser. As prepared as the demons might have been, they wouldn't have expected something like this.
The Light and Dark Elements, as well as the weapon intents, brimmed from Rean and Roan. However, that wasn't all! To add to the power of their next attack, Spatial Power began to gather within the weapons and the elements themselves. The twins were still nowhere near the level necessary to merge elements with Spatial Power. But mixing them was what made Void Tempering Realm experts so much stronger than Transition Realm ones.
Rean and Roan then charged toward each other as their powers raged! The strength of their attack was so great that even the space around the two weapons seemed to contort without the twins trying to do it themselves. Yet, just as the twins' power were about to clash...
*Vup! Vup!*
The twins disappeared from the Dimensional Realm, appearing on the right and left sides of the demons like two huge suns of black and white light!
'Sun and Moon Obliteration!'
"What?!" Rlakux's group was taken aback by that sudden appearance. Their Divine Senses simply hadn't picked up anything at all before the twins were already all over them. Unfortunately, it was too late now.
*Boom!*
The two attacks connected before neither of the demons could prepare any defenses other than using their Divine Energy to protect themselves. They didn't even have the time to use the power of the souls they had absorbed.
Rean and Roan had aimed the attack right in the middle of their group... well, almost. They still focused on the center of the explosion, targetting the three demons behind Fratekla and Rlakux. It's just that the area of the explosion of Dark and Light Elements was so big that one might as well say that they attacked the center.
*Arrrrggghhhh!*
*Vun, vun!*
*Bang, Bang!*
Rean and Roan were shocked by the power of Sun and Moon Obliteration. It was so big that both of them were sent flying like cannonballs, hitting the wall of the building and the ground. Roan was the one to hit the ground, creating a small crater. As for Rean, he obviously hit the wall of the building. It's just that the Clenhest Stone it was made of only slightly trembled. Sure enough, Rean's body didn't leave a single mark on it.
They were lucky that they already had a Fourth Grade StarBody. Otherwise, they might have even died, especially Rean, since he hit the sturdier surface of the wall than the ground Roan did.
Rean then looked at the Black Star in his hand and saw the cracks on it. Even his best achievement in blacksmithing so far couldn't completely resist the power of Sun and Moon Obliteration. 'Holy shit! Let alone the amount of Light and Dark Element Roan and I can gather now, just the addition of weapon intents and Spatial Power made this attack become practically a suicide bomb. Just how powerful is it?' At the same time, he started to gather Light Element to quickly heal his injuries.
Roan heard Rean's words through their Soul Connection, replying, 'We have seen the battle between two Peak Stage Space Bending Realm guys quite a few times. I would say that Sun and Moon Obliteration was at least similar to one of Olly's best attacks. No wonder even the two of us were injured by it, although we weren't the main targets. It's a shame that it's not viable during normal circumstances. After all, we also suffer from its aftereffects.'
The twins then used their Divine Sense for the first time, wanting to check and see how the demons fared.
