"...no, it's fine." Sona took a deep breath, then looked at Masa softly. "Thank you for your help, Masa."

  "It's fine." Masa nodded and asked, "But I don't think this situation is normal. You should ask for your sister's help sinething simir might happen iure." If he wasn't there, what would happen?

  At the same time, he wondered whether those rat youkai even appeared in the inal story.

  Or rather, was it his appearahat ged the story?

  As Masa was ihought, So flicted about asking her older sister for help, but she wasn't so stupid as to take care of everything by herself, sidering the dahat she had entered before and the possible dahat might e iure. More importantly, like Masa, she also felt that this situation was weird as she was being surrounded and trapped. At the same time, how could such a rge number of youkai enter Kuoh City, which was surrounded by barriers?

  More importantly, Kuoh City was a town that was governed by two little sisters of the Freat Satans!

  Who dared to make trouble with Serafall and Sirzech with the bag of Sona and Rias, who were the two governors of this city?

  Even the leaders of Youkai of East a Japan wouldn't dare!

  Yet, how could those dirty rodent youkai dare?!

  "I will talk to my sister."

  "That's good."

  Watg his relieved expression, So helpless, realizing that the one eak wasn't Masa but her. Turning her head, she looked at the destru created by Masa.

  The inal shape of the mansion could no longer be seen; everything was in ruin, and the forest that surrouhis pce was all smashed, creating a deep and rge hollow that was deep enough to form a ke. More importantly, the rodent youkai, which made her troubled and nervous, were all turned into uified meat that was mixed with the soil, utterly crushed by Masa.

  'This... isn't his power a lion taming?'

  While Sona was fused, Masa thought about the ability of his Ton Ton no Mi.

  Frankly, he had many ideas on how to develop this Devil Fruit.

  The first one, which was the easiest way, was to increase his body weight for an attack. It was simple, but it was also destructive.

  Previously, he might say that he would increase his weight with an illusionary weight, so the physical requirement that he needed wasn't high, yet he could make a dangerous attack. Yet somehow, along the way, he decided not to take a shortcut sihe heavier he was, the harder his defense was.

  Increasing his weight meant that he was either increasing the gravity on his body or increasing the density of his body.

  Naturally, Masa chose the tter sihe denser he was, the harder his body was, increasing his defense so that he would bee invulnerable.

  Still, many might not uand, but what was density?

  Density is a substance's mass per unit of volume.

  If it was still hard to uand, you could imagine one kg of steel was much more dangerous than one kg of tofu, right?

  The two had simir weights, yet the steel was much harder, stronger, and smaller thaofu, and it was all due to the density of steel being much higher thaofu.

  This was why the increase of his physical ability was needed sihe denser he was, the harder it was for him to move.

  Still, due to the density of his body, as his weight increased, his defeurally increased, and his body could even be harder than a diamond the more his weight increased.

  With this ability alone, he khat he was simply unmatched in close bat, but he felt that this wasn't enough, so he thought of a seethod to make the Ton Ton no Mi stronger, which was to increase the weight of others, whether they were non-living or living beings.

  If it was in the world of One Piece, it might not be so easy, as there were world rules, which made the development of the Devil Fruit harder, but this was the world of DxD, there were no such rules at all, especially when Issei could create a pervy teique where he could destroy the clothes of female, or talk with boobs as he wished even though he was just a normal human in the beginning.

  This method was what he had done when Masa from the world of One Piece came to the Florian Triangle and suppressed the rge waves by increasing their weight to calm them down.

  Whether it was water, air, or any non-living beings, he could increase their weights as he wished to be, but if it was a living being, it might ime for him to do that, yet this was enough, right?

  Still, like Masa from Mahouka, who kept developing the Pika Pika no Mi, he also thought of furthering the Ton Ton no Mi, which led him to the third method, which was to trol gravity.

  Weight = Mass x Gravity.

  Weight is the bination of mass and gravity, so logically, he manipute those two factors within this world.

  heless, Masa had been fog on the aspeass, and he had yet to train mu the aspect of gravity.

  Yet, even so, it was enough for him to destroy everything as he had previously, increasing the weight of the air to 250 tons or that of a Statue of Liberty, and he created a pressured air bst that destroyed everything.

  Still, he had to say, this destru was a bit too much, he thought.

  "If you want to ask, then ask, Sona-nee."

  Masa looked at Sona, eared hesitant.

  "Um... Masa, that was..."

  "My eique."

  "eique?" Sona was dumbfounded.

  "After all, even if I have a lot of powerful lions, I still want to rely on myself to fight, so I developed a eique."

  "And that's is...?"

  Everyone looked at Masa, curiously w what kind of teique Masa had used as he could cause such destru that eveed ahquake iy.

  Yet, while it was quite exaggerated, they also felt relieved sihey khat Masa was angry at them and wao protect them, so this was why he made su attabsp;

  Still, in the world of the supernatural, strength was absolute, and those with strength were definitely favored.

  "It's a secret."

  "....." Everyone.

  Masa yawned and said, "I feel a bit exhausted from the trip. Do you mind if I rest first, Sona-nee?"

  "...."

  Sona eechless, but she also khat her question was rude as Masa had no obligation to tell her everything, yet there was no doubt that she was curious about Masa's teique. "Tsubaki, please take care of him."

  "Yes, Sona-sama." Tsubaki nodded softly, then looked at Masa. "Masa-sama, please follow me."

  "Thank you." Masa the, following Tsubaki, who used teleportation magic to the pce where he would rest tonight.

  Still, as Masa and Tsubaki had left, the rest looked at the rge hole and asked, "Sona-kaichou, what should we do with it?"

  "Let's just buy it."

  The destru caused by Masa was too much, and it was impossible to fix, so she might as well buy this pce. Still thinking about his might, she became even more curious about him.

  Yet, when she was in the middle of a deep thought, a familiar magic circle appeared nearby, and she saw her best friend, who was also one of the governors of this city.

  "W-What is this?!"

  "T-This much power..."

  "Sona, who had caused all of this?!"

  "....."

  Looking at her best friend, beautiful crimson hair, and voluptuous body, Sona somehow didn't want to tell the truth.

  heless, those creatures who wao set up a spiracy withiy didn't feel sad ry with the death of those dirty youkai.

  "What a useless creature."

  "As expected, they are so weak!"

  "I have told you before, Kokabiel-sama. Moreover, they are too dirty and disgusting!"

  Among all of those people, all of them looked at their leader, showing their dissatisfa with using such a dirty creature as Kyuuso.

  "You don't have to worry. This is the st time, but more importantly, are you sure that st night was just ahquake?"

  Staring at the fures before him, the man asked.

  "Yes!"

  "Okay, then."

  Hearing those answers, the man also simply ighe problem st night and focused on his ambition to create the Great War!
