We can do it!

When Rias and her peerage members came to the school, Sona and her peerage also came.

The two of them gathered together to discuss the war they were about to have with one of the leaders of the Fallen Angel, Kokabiel.

"What about Irina?" Issei asked Sona.

While Asia had tried her best to heal Irina, she couldn't do so. While her Sacred Gear, Twilight Healing, was a powerful healing type of Sacred Gear, it definitely wasn't perfect.

In the end, Rias decided to ask Sona to see whether there was something that could help Irina.

Sona told Rias she had "Phoenix Tears," so she brought Irina to her house.  Still, after she healed Irina with "Phenex Tears" from her husband, she returned to the school as there was a big battle that they were about to face. 

Naturally, when Sona and her peerage members returned to school before Rias said anything, Issei spoke in a great hurry, which made his tone rude. It was like Sona had owed him. 

"How is Irina?!" 

Yet, Sona didn't say anything and shut her mouth as if she didn't notice Issei's presence.

"......." Issei.

Rias sighed, then asked, "Sona, what about that exorcist?"

"I have placed her at my house." This time, Sona talked. "You are lucky that my husband has given me a share of "Phenex Tears." If not..."

If not, then Irina might cripple or, even worse, die.

Riser had been living at Sona's house for several days, and naturally, it was impossible for him not to make "Phenex Tears" for his wife. Anyway, it was easy for him to make them, so he made a bulk for her in case of a crisis.

This time, for this battle, Sona also bought a crate filled with "Phenex Tears," which was made by Riser.

"Just in case, you should each bring two."

"Thank you." Rias was grateful to Sona and Riser since she knew how vital the "Phenex Tears" was.

Even though Issei was a bit dissatisfied, he said nothing this time.

While it was true that Issei hated Riser, he also knew how amazing the "Phenex Tears" was. After all, he also had consumed it in the past. While he felt that Riser might have ripped him off, there was no doubt the effect was amazing.

Asia's Twilight Healing was good, but Asia wasn't omnipotent.

In case an emergency situation happens, they could heal themselves by drinking the "Phenex Tears."

"By the way, have you called your brother?" Sona suddenly asked.

"...you want me to call my brother?" Rias felt reluctant. Even though she was about to face a legendary figure that appeared in the bible and the book, she felt that there was no need for her to call her older brother.

While it was true that Kokabiel was strong, she didn't think that they would lose, especially when she was quite strong, and the strength of her peerage couldn't be underestimated.

"I have called Sirzech-sama. It should be an hour before they arrive."

Akeno was the one who answered Sona's question.

"Akeno!" Rias looked at Akeno in displeased. 

"Rias." Akeno looked at Rias with a solemn expression. "We are about to face a dangerous enemy."

"I know..." While Rias felt quite unacceptable to rely on her older brother since it had happened, then that was it. "How about you, Sona? Have you called your older sister?"

"I do. She should be with your brother, ready to go to the human world."

"Is-Is that so?"

Rias was surprised by Sona's willingness to ask for help from her older sister.

After all, similar to her, Sona also didn't wish to rely on the strength of her family and wanted to be seen as an individual instead of the heir of the Sitri House and the little sister of Serafall Leviathan.

Yet, had Sona changed?

The answer was yes.

Due to her relationship with Riser, Sona had changed, and she knew that she needed to see the big picture instead of focusing on her ego.

If her ego might cause the death of many, then she might as well erase that ego.

"How about Riser? Have you called him? Is he still at that mountain?"

Naturally, Rias knew that Riser had gone once again to visit his peerage members, who were in the middle of training.

"I was about to call him."

If Riser was around, then they would feel at ease since they had seen how strong he was.

Kokabiel might be powerful, but could he face Riser's blue fire?

However, when Sona was about to call him, Issei suddenly said, "Wait!"

Sona frowned, hearing Issei's words, but she didn't say anything and just looked at Rias with an expression, "Look how lawless your slave is."

"What's wrong, Issei?" While Rias was a bit exhausted by Issei's antics, she was still calm and willing to listen to him. After all, Issei's potential was there. As the holder of the "Boosted Gear," even if he was a pervert, he could become strong.

Moreover, Issei was her peerage member and liked how she was educated as the heir of the Gremory House; she would think of her members as her family.

"Do we need to rely on him, Buchou? Don't you think that we're strong enough to handle this fallen angel by ourselves?" Issei suddenly said in great fervor.

"...are you serious about what you are talking about, Issei?" Rias narrowed her eyes.

"Yes, Buchou!" Issei nodded without hesitation. "I have trained myself hard! I have become stronger! I am not like before! Moreover, I am not alone! I have you, Asia-chan, Akeno-san, Koneko-chan, and also Kiba! We are not alone! We can do this together, Buchou! We can defeat Kokabiel by ourselves!"

There was no way for Issei to let this chance go!

Issei had been showing many embarrassing moments, and this time, he was going to show everyone that he wasn't useless!

He is the holder of the legendary Boosted Gear!

He was going to become Buchou's strongest pawn!

Then, when they received their victory—

'Hehehe... Buchou's boobs~!'

As long as he won this battle, there was no doubt that Buchou was going to spoil him a lot like before, pressing her boobs against his face and letting him touch those beautiful boobs!

Right now, he believed that he could even defeat a God!

Yet, while Issei was excited and full of confidence, the others weren't that confident, especially Sona and her peerage members.

Even Koneko, Asia, and Akeno couldn't have that confidence.

Yet—

"Buchou, let us do this by ourselves!"

"Kiba?" Rias looked at Kiba in surprise.

Out of all her peerage members, there was no doubt that Kiba was the calmest among everyone.

Kiba was also reliable, so it was also due to this that Rias was surprised by Kiba's support toward Issei's decision to handle this battle by themselves.

"Yes, I believe that we can do this, Buchou."

Kiba supported Issei's decision since he was afraid if Riser came, then his chance to have revenge might disappear. There was an enemy that he had to defeat no matter what, so if that enemy was defeated by Riser first, then how could he accept it?

Moreover, Kiba also didn't think that he would lose.

Rias didn't say anything and fell into silence.

"Buchou! We can do this! We even have "Phenex Tears" with us!" Issei grabbed Kiba's arm happily, showing how happy he was with Kiba's support.

Rias thought for a moment before she nodded.  "Okay."

"Rias!"

The one who chided Rias wasn't Sona but Akeno.

Akeno looked at Rias in disbelief since she didn't expect that Rias would follow the stupid decision made by Kiba and Issei.

"Akeno, don't stop me. I also believe that we can stop this difficulty with all of us." Rias was also confident. No, she thought that it was an excellent chance to show her power so that Riser would be impressed by her might.

"Are you sure about this, Rias?" Sona asked with a frown.

"Yes, Sona. I have made my decision." Rias nodded. "I will be the one who faces Kokabiel and the rest. Please help manage the barrier in case the damage caused by our fight won't spread to the surrounding area."

Nevertheless, Sona hesitated, but Rias pressed her even further. "Believe me, Sona. I can do it. No, me and my servants can do it."

Unlike Issei, Rias had a certain charisma due to her pure devil heritage.

"You should know everything might be too late if I don't call him now, right?"

Even though a devil could teleport from one place to another due to the teleportation circle, it didn't mean that they could teleport as much as they wished.

Riser was in a far-away place, on the mountain, so if he wanted to use the teleportation circle, he needed to go to the place where it was connected or marked to the teleportation circle or be summoned.

Unfortunately, he didn't make a summoning scroll, so in the end, he could only go to the place that was connected to the teleportation circle.

However, if Sona called him now, then Riser could come after a while, but if she didn't call him, then—

"There is Serafall-sama and Sirzech-sama who will come to us in an hour. No need to worry, Sona."

As expected, when Serafall and Sirzech were mentioned, Sona's expression was quite at ease since as long as the two came, their safety was guaranteed.

"...I will believe in you then."

"That's right. Believe in me."

Rias smiled and then looked at her peerage members. "Since we have decided to fight Kokabiel, then we have to win. Let's show them the power of the Gremory House!"

"Yes, Buchou!"

All of them answered with a high spirit and thought that they could do this battle.

Then, as they finished their preparation, their battle started!
