Chapter 34: The Promise to Keep

Third Person POV

It had been two weeks since Era passed out from the lack of Spell Energy in her. At the moment, Cornelia and Myla had come to do a check for the first time. Yusei was sitting at the end of the bed watching Era as Cornelia and Myla did their work.

Cornelia was scanning Era's body for any internal problems due to the lack of energy that was the cause of this, two weeks ago. Myla was using a bit of her energy to help replenish Era's a bit more. But Yusei knew they couldn't do too much. Putting foreign angel's Spell Energy in another angel is risky and too much could very well kill the energy needed angel.

Cornelia pulled back suddenly as she hit around Era's lower abdomen while Myla stopped confused by the sudden jerk from Cornelia and she was also done with her sharing.

"What's wrong, Cornelia?" Myla asked.

"I was doing a scan when I felt another angel's life force here," she explained.

Myla raised an eyebrow and did her own scan. She pulled back confused and stated, "Okay, that's just weird." They looked at Yusei. "Any clues?"

"Yeah," he answered. "I found out about it when I talked to our lord and someone else."

"Who's 'someone else'?" Cornelia asked.

"The only reason I was able to get the Underworld Curse Gem's poison out of me was because his highness took me to the tomb of the first Guardian Angel of Light and apparently she stayed there to watch the angels live on until she didn't need to be around anymore," Yusei started and he was about to explain what Arietta told him when Myla cut him off.

"Wait, wait, wait, are you saying you met the original Guardian Angel of Light?" she asked.

"Yeah," he answered.

"And… what did she say exactly?" Myla asked as both she and Cornelia seemed to be in a state of shock. "Is it part of why Era is taking longer than it should for her to wake up from this?"

Yusei nodded. "The first Guardian Angel of Light's name was Arietta. She had a mate as well," he started and they looked at him intently. "According to her, after she first became mates with the male angel, she began to weaken in power a bit. It wasn't until later she found out why." He paused prompting the two female angels to give him prodding looks. "Arietta said that when a female angel becomes mated with male, the male sends some of his DNA into her and…"

Cornelia cut him off by asking her realization, "Are you saying Era is pregnant?" Yusei gave a small nod.

"How? She doesn't look like it at all," Myla asked.

"Arietta said pregnancy isn't the same for angels as it is for humans," he explained. He looked at Era's peaceful face in her sleep. "And I'm worried about how Era will feel about it."

"Is there a way to get it out? And does this happen with every female angel who has a mate?" Cornelia asked.

"I asked a similar question," Yusei replied. "Our lord said that it has only ever happened to the Guardian Angel of Light. He also said that since she has so much power, it would be dangerous and potentially deadly to take it out of her now."

"So there really is no way out of it," Cornelia responded.

"But it would explain how she lost the energy and is taking so long to recharge it. She is also sharing the power with a child inside her," Myla stated as the two Healer Angels looked at each other. "I just hope Era will be able to accept it."

Yusei tilted his head down in frustration. He wished he could've helped his mate better and wanted more than anything for her to wake up. He couldn't stand not having her to tell this to and the worry over everything that had happened was overwhelming.

"It'll be alright, Yusei," Myla told him and he looked at his two angel friends. "Era's tough and she knows how to push through things, even if she doesn't want it what she has to push through. And I'm sure that once she gets to hear the idea a bit, she'll grow to accept it and be happy with it."

"After all, it's also from the angel she loves and cares about most," Cornelia added and gave him a smile. Yusei returned her smile with a grin.

He then asked, returning serious again, "Any idea how much longer before she'll be able to wake up?"

Myla did a scan and answered, "Another day, at most. So not much longer. That's saying if she keeps the steady replenishing rate she's at."

"Good," Yusei responded.

Myla's locket went off. "Cornelia, we're needed back at council," she stated.

Cornelia nodded. They looked at Yusei. "Yusei, take care of her and keep an eye on her. She'll need you more than ever now," she told him.

Yusei nodded in acceptance and the two angels took off. He got closer to Era and gently grabbed her hand with his right hand. "Don't worry, Era. I'll never let you be alone and go at this alone. I promise," he whispered and used his free hand to gently hold her face. He touched his lips to her forehead and thought, 'I love you too much to let you do that.'

. . .

Yusei waited in the room, just sitting next to Era as the time ticked by. Jack, Bruno, and Crow stopped by, checking in on Era and asking what Cornelia and Myla had said. When he explained everything, though he left out the pregnancy because they still didn't know about him and Era being mates, they seemed shocked about her energy forming slower than it should but relieved that she should wake up soon.

"So where did Cornelia and Myla go?" Bruno asked.

"They were needed back in the Afterlife," Yusei explained. "They were able to finish their help here for now, though."

"Do you think she'll be alright?" Crow asked.

"Yeah," Yusei answered.

"I think you can leave her for a bit, Yusei," Jack stated. "I don't think Brehnam is going to come after her when you'll be able to feel his energy in a second and come in here." Yusei looked back at Era.

"Don't worry, Yusei. She's safe here," Bruno told him.

He closed his eyes calmly. "I know. I'm just worried about her," he responded. "That's all."

"You really do love her, don't you, Yusei?" Crow asked.

"More than I can put into words," he replied opening his eyes to look at Era again.

They went silent for a bit. But eventually they began talking again, the three humans trying to keep the topic off of Era. They knew it would only cause Yusei to hurt more. They already knew he didn't like not being to help Era as much as he possible could without killing himself and risking killing Era. But what the humans didn't know was that it was also that Yusei didn't want to leave Era alone in case she woke up sooner rather than later. He knew that Era would want to see him before anything else and he wanted to be there to help her a bit.

Eventually though, Jack convinced the other two of Yusei's friends to back off of Yusei and they left. Yusei just turned to Era again, worry in his eyes.

After waiting another hour, Yusei's worried eyes turned to ones of relief as his mate's eyes opened. She looked at him, seeming relieved and confused.

"Yusei?" she called quietly.

"I'm here," he replied calmly. She began to sit up. "Easy, Era." He pushed her down again gently. "You need the rest."

"What… happened?" she asked.

"You used up too much of your Spell Energy," he explained. "Why didn't you tell me you were that week? I could've helped."

"I didn't want to worry you," she answered looking to the side a bit.

"Era, you were in a coma for almost two weeks because you used so much energy," Yusei retorted, shocking the angel and making her look at him again. "Do you really think that you hiding how week in Spell Energy you had was going to be better for me?" She averted her gaze from his, unable to hold it. Yusei gently grabbed her face to make her look him in the eyes.

Before Yusei could do anything, Era sat up so she was close enough to kiss him. As soon as their lips met, the male angel brought her closer to him, wanting nothing more than to hold her close like this again, after so long of worrying.

Time seemed to slow down for the two angels and they couldn't tell how long they kissed before Yusei could back so they could breathe. And instead of lying back down, Era leaned into Yusei's chest as he held her.

"Don't worry me like that again, Era," he whispered as he pulled her closer. "Please."

"I'll try not to, Yusei," she agreed, listening to his heartbeat. She noticed, though, that his heartbeat was faster, like he was nervous. She slowly looked at him. "Yusei, is something wrong?" He looked to the side, not sure how to tell her what happened and what was said between him, the Crimson Dragon, and Arietta. "Yusei?"

"It's just…" he paused and she looked at him. "When you first blacked out and I got you here, the Crimson Dragon called me to meet him. He took me to a secret tomb in the palace. It's where the original Guardian Angel of Light lays. But during that time, the spirit stayed with us, in the tomb. And I got to meet her." Era's eyes widened in shock. "She explained to me what really happened with the first angel to be born from her, and how it happened."

"How was the first angel born?" Era asked.

"Her name was Arietta and she had a mate," he began but stopped.

"It's okay, Yusei. Just tell me," she assured him.

Yusei looked in her eyes for a moment, looking for any signs against those words. The only things he saw were readiness and worry. "According to Arietta, this only happens to the Guardian Angel of Light as far as her and the Crimson Dragon knows. When she gets a mate, the male sends his DNA into her and she…" he stopped, not wanting and unsure how to finish.

Era looked down for a moment. "Are you saying I'm… pregnant?" she asked in the lowest whispered.

"I'm sorry, if I had known, I would've…" he was cut off by Era placing her lips on his again.

When she pulled back, she said, "I'll be okay, Yusei. As long as you're there with me through all of it, there to help me raise the child too, I'll be fine."

"Are you sure, Era? I mean…" he stopped again.

"I'll be fine, Yusei. You don't need to worry about me so much," she replied.

"Worrying is all I can do about you, Era," Yusei retorted. He pulled her in close to him again. "I promise, though, I'll stay by you with everything there is. I'll never leave you alone, no matter what."
