Regardless, Kira undid his magic and didn't regret his choice, as he wanted to show Lucy what one could do with Celestial Spirit Magic. By using the power of Virgo and Loke, he combined them, using them within him, which made him able to use their combined attack.
The chain magic of Virgo was combined with Loke's Regulus, the light magic that could empower everything; then, along with Virgo's earth magic that specialized in creating a hole, Kira created a new magic known as "Laniakea," the powerful chains that could be used to bind or tear anything apart.
Still, while this magic appeared complicated, all Kira did was turn Virgo and Loke into something similar to Erza's magic armor and weapon.
Erza's magic was requip, which made her able to use all the magic armors and weapons that she kept inside her dimensional storage and wear them instantly, using them to defeat her enemy.
On the other hand, Kira made Virgo and Loke trust their powers in him, creating magic armors and weapons from their combination attacks.
If Kira had to say, the name of this technique was known as—
"Astral Dress."
Still, while Kira didn't use all of his Magic Power that had been recovered after he had a deep kiss with Lucy, he felt quite exhausted, but when he was about to sit down on the ground, trying to calm his nerves that were tense, someone caught him.
"Are you okay, Kira?"
"....."
Kira looked at Erza, who helped him to stand up, and she asked that question with concern for him. He knew that she was under a huge misunderstanding that he wasn't fine and completely exhausted, but it was obviously impossible for him to use all of his powers, since if he did so, he would cause huge destruction in the area.
Unlike Natsu, who couldn't care about the debts or anything, Kira couldn't do that.
Regardless, facing Erza's concern, Kira nodded. "Yes, thank you."
"No, I am the one who can't do anything. Even though you have entrusted everything to me..."
"...."
Watching Erza, who started to blame herself like a bundle of negativity, Kira was helpless, wondering why she had to make a tired man comfort her.
"Then, next time. Protect me well."
"...."
Facing his gentle smile as Kira asked her such a request, Erza was stunned, before she nodded with determination. "I will."
Kira raised his fist, and she hesitated for a moment before meeting that fist with hers, with a light smile on her face. They might have just met, but she felt like she could trust him, and unlike the others, who treated her like either a monster or a woman, he treated her how she wished people should be, which made her comfortable around him.
It was like... Kira truly believed that she would help him, and naturally, she wouldn't betray that trust!
"...."
While Kira wasn't sure what Erza was thinking, he knew that this woman had started to overthink.
"Happy, what's wrong? Are you okay?"
As Natsu asked this question, Happy wanted to say something, but he felt Kira's gaze on him.
"N-Nothing!"
Only Lucy was quite shy and didn't dare to meet Kira's eyes.
"What's wrong?" Erza asked with confusion.
"Nothing." Kira wanted to get away from Erza since he had to say her body, which was covered with an armor plate, was too hard and uncomfortable!
"It's just... can you let me rest somewhere soft? Like that chair."
"Oh."
Erza, who planned to let Kira rest on the soft parts of her body, stopped, then moved him to the chair within the train as she tried not to let him see her expression since she was sure that her face was so red!
Unfortunately, Kira missed all of that!
Regardless, everything was solved, and the Eisenwald's act was stopped, and they were able to defeat all of them before this evil group of mages implemented their evil plan.
As a group of soldiers from the city and the Magic Council members came, they quickly helped Kira and his group. They thanked Fairy Tail, along with all the passengers and everyone they saved.
Yet was it over?
What were the members of the Eisenwald planning to do?
While Erigor and his group couldn't do anything and had been defeated, all of them still needed to know what everyone on the Eisenwald planned to do with the Lullaby.
However, it had nothing to do with Kira, as he rested on the side of Lucy, as he knew that he had to talk over his decision to kiss Lucy.
Why did he kiss her?
Was it just for the battle?
Wasn't there a different meaning for it?
Yet, before Kira could say anything, Lucy said, "It's fine."
"...what do you mean?"
"I mean... I understand the situation, so you don't have to worry." Lucy's expression was that of a sincere person as she looked at him softly. "I don't mind if it's you..."
"....."
What did Lucy mean?
Her words were ambiguous, and they had broad meanings that Kira could interpret in many ways.
Was she okay with him kissing her?
Or was she okay with remaining as they were as Kira dated Mirajane?
While Kira wanted to ask her further, an exclamation from the side interrupted his thought.
"What?!"
Everyone was shocked when they learned what the Lullaby was from a member of the Eisenwald.
"So, Lullaby is...?"
"Yes, it is a cursed flute that can create a sound magic that will cause all the people who hear it to die except for the user."
As they followed Kira's words, forcing the member of the Eisenwald to talk, if not, then they would beat the guy up, the member of the Eisenwald cried, depressedly, wondering who the Dark Guild was among them.
As a member of the assassination guild, Eisenwald, he was ruthless, yet the members of Fairy Tail were on another level!
"So, you plan to hijack the train, then use that Lullaby on the station?"
After the disbandment of the Eisenwald, as its guild master was caught, the members of the Eisenwald decided to take revenge by using the Lullaby, showing the world the true pain and who was the true ruler of this world!
Yet, unexpectedly, the member of the Eisenwald laughed. "Hahaha..." Only he stopped when Erza beat him. "Ah, I am sorry! I am sorry!"
"Stop, Erza! You are going to kill him!"
Erza wanted to beat the member of the Eisenwald, but was quickly stopped by everyone. "Hurry up and tell me, or else I will use my blade to cut part of your body!"
Shudder!
"....."
Which part?!
"I will tell! I will tell!" A member of the Eisenwald panicked!
"It's the meeting of the guild masters! We will use the Lullaby to kill all the guild masters who participated in that meeting!"
Shouting with all of his might, a member of the Eisenwald ignored everyone's reaction and said, "Kage, our member should be on the location now! He is a user of shadow magic, and he has escaped from a battle before! By now, he would be on—"
BAAAAAAMMMM!!!
"You piece of shit!"
Erza was enraged as she beat the shit out of the member of Eisenwald!
"Stop! Stop! Stop!"
Kira quickly pulled Erza away, stopping her. "We have to go now! We don't have time to stay here!"
"But how?!" Erza was in a panic since she knew that it was too late!
They had wasted their time on this place for too long, and this Kage should have arrived where Makarov was!
If it were any of the other guild masters, Erza wouldn't be so panicked, but if it were Makarov, it was a different matter!
Makarov was like a parent to her, a family. If she lost him—
"Can you fight?" Kira asked.
"....."
Erza was stunned, but then she nodded with an unwavering gaze. "Yes."
While feeling helpless, Kira prayed once again and confirmed where Kage was, then a magic circle appeared on his back before two angelic wings grew there.
"Ah, that's my magic!" Happy was surprised.
"Huh?!" Natsu was surprised. "Is Kira also a flying cat?!"
"...." Everyone.
"Let's go."
As Kira said, after he ignored Natsu, Erza directly jumped onto him, hugging and dangling him like a lover.
"...." Lucy.
Yet, no one cared about those small problems as Kira started to flap his wings and then soared into the sky. "Don't bite your tongue and hug me tightly—"
Only, he regretted his mouth since Erza's body wore armor, and her strength wasn't weak; it was so painful when she hugged him.
"Y-Your armor is too heavy and it is so painful when you hug me..."
Kira could bear Erza's strength, but her armor?
It was too much, he thought.
Yet, his words made Erza hesitate as this armor that she had always worn had a different meaning for her, but as she thought that she had to save Makarov, she knew that she had to release her armor, so while she was a bit afraid, she released her armor, and kept it inside her dimensional storage.
'No...!'
Unexpectedly, as soon as Erza released her armor, she felt an intense fear as she was unable to feel, and felt a fear as if she was about to be swallowed by a nightmarish monster—
'Huh?'
However, at that moment of fear, a powerful arm wrapped her body tightly.
"Believe me."
As Erza released her armour, Kira didn't hold back either and used Happy's magic, Aerial, which he combined with High Speed Magic, and also a burst of fire magic from behind, which increased his speed further, and wind magic that protected them from drags and erased air resistance.
BOOOOOOOOOOOOOOOOOOMMMMMMMM!!!!
As the sonic boom echoed within the space, everyone could only stare at the two in a daze, yet deep inside, they prayed for Kira and Erza to be successful.
However, as Kira focused on his magic to save Makarov and the other guild masters, who participated in the meeting, Erza stared at him in a daze, then buried her face deeply onto his chest as if she wanted to remember this feeling where she wasn't in fear of anything as she had him by his side.
