Editing Shinmai Maou no Keiyakusha:Volume 7 Chapter 4 (section)

===Part 5===
From the beginning of her duel until the very end, Naruse Mio never used the power of the former Demon Lord Wilbert. Now, she was using it to stop Basara. —Mio didn’t understand why Basara was able to use the power of gravity. In any case, Mio’s intuition told her that aside from the interference of her own gravity magic to supress Basara’s gravitational power, there was no other way to stop Basara in his current state. —Last night, before Basara left the guest house, he confessed to Mio and the others about something. Although the possibility was very low, in the off-chance that Basara attempted to kill Leohart — they had to do everything possible to stop him. Mio and the others didn’t understand why, but they knew that Basara had his own reasons, and so they immediately agreed to Basara’s request. Seeing Basara act so seriously, it was only natural that they were unable to refuse. At least for Mio, Basara was her absolute master — and an important family member. Moreover — of all the people present, Mio was the only one who was able to enter this space. And that was why the burden of fulfilling this request was entirely on Mio’s shoulders right now. It wasn’t for the sake of helping Leohart, but to stop Basara from losing control, and at the same time, she also had to maintain control of her own power and stay conscious. After all, her target was Basara, so all she had to do was prevent his movement. So, Mio carefully adjusted the Demon Lord’s power in her body. —In the past, Takigawa had advised her to get stronger, to the point of being able to kill Basara in the very unlikely event that she had to. However, Mio was still not at that level yet.

''…But.''

This was enough. Because everyone had forged a deeper bond with each other, they had powerful feelings that would not break no matter what came at them. Everyone believed in those feelings and decided to treasure each other, and live together. Hence — she had to stop Basara no matter what.

“Basara…it’s enough already.”

Mio softly called his name, and she pressed her chest against Basara’s back — as if to move their heartbeats closer together. The most important thing was to tell him that she was here. Just as Naruse Mio accompanied Toujou Basara in the past, that would not change from here on either. Then — Mio straightened her back, and spoke in a whisper that was only audible to Basara

“—Please, onii-chan.”

The curse of the master-servant contract had not activated — but Naruse Mio still addressed Basara in that way. She knew that when she called him like that, that Basara would definitely respond.

''…Indeed.''

Because Basara was that kind of person, Mio was that kind of sister, a loyal submissive girl who loved him. This strong emotion that filled the heart would never abandon her.

“………”

Brynhildr was slowly lowered…it was not swung, Basara had loosened the grip of his arm, and he slowly lowered it. After letting out a heavy and long sigh, he put his left hand on top of Mio’s hand that was on his chest.

“……Mio.”

It was the normal Basara who turned around to call her name. Different from when they had first met — the current Basara saw Mio as someone much more precious to him now. So—

“———”

Naruse Mio could no longer supress the overflowing emotions in her heart, regardless of the number of people watching them from outside the fighting space. She tightly embraced Basara once more. —An important fact was conveyed to everyone who watched this scene. She did not belong to the Moderates faction or the Current Demon Lord faction, and neither did she belong to the Council. For a long time now, Naruse Mio — belonged to Toujou Basara. Outside of the fighting space that Basara and the others were in, was silence. The audience members who were watching the broadcast of the inside were all speechless. —Mio’s interference had interrupted the duel between Basara and Leohart. But no one dared to clamour or say that Basara should be disqualified unlike the time when Zest had done the same. Because, no matter what the reason or intention, she had saved Leohart from Basara.

[———]

In the broadcast, Basara stretched his hand out to Leohart, who was trying to stand up.

[………………]

After a long silence — Leohart slowly grabbed his hand. The Current Demon Lord, the previous Demon Lord’s daughter, and the son of the man known as the God of War all stood together in this moment. No one could have imagined that something like this would happen in the decisive battle between the Current Demon Lord faction and the Moderates faction. This scene — caused every single person in the arena to envision a future in which the Demon Realm was no longer at war. However — there were some people who held differing thoughts, and were waiting for this development and the arrival of such a situation.

The son of the God of War Jin Toujou, the wielder of [Banishing Shift], Toujou Basara. The only daughter of the strongest former Demon Lord in history, Naruse Mio. The striking young hero who had become the new Demon Lord after Wilbert’s death, Leohart. What those people were waiting for — was a situation in which they could take down all three of these people.

“—The sacrifices are in full attendance. Eat to your heart’s content, Chaos .”

At the same time, when Mardones said that while in the Council’s special viewing gallery as he looked on, ‘that thing’ began to take action.

In the next instant — a burst of white light flashed through the fighting space that Basara and the others were in. It was immediately followed by vigorous tremors and explosions on the ground.
