Austin: Strengthen your magic further to stop that enormous comet.
Harry: Yes.
After a few moments, their magic was depleted, and they were out of breath.
Harry: It seems we have no hope left.
Austin: Is this the end?
Chief: Let's just pray for a miracle.
Lisa: Is it really over?
People of Aoyama: Look, someone is flying towards us.
Austin: Who could it be?
Harry: Wait? Is she seriously going to collide with the comet?
Hana collided with the comet and emerged on the other side. She then descended among the people, surprising them all.
Lisa: You?
Harry: What are you doing here?
Hana pointed her hand at the comet, causing it to stop its descent.
Austin: She stopped it all by herself, while we were struggling earlier.
Hana: I can't bring it back to its origin, but I can destroy it.
Lisa: Hey, are you serious?
Harry: Don't delude yourself, Hana. You're just a loser.
Hana: I believe my magic... no, my aura, is enough.
Austin: What did you say? Aura?
Hana: Yes, is there a problem with that? You should all escape; I won't be able to protect you once this breaks into smaller pieces.
Lisa: Don't delude yourself, Hana.
As Hana slowly shattered the comet using her psychic power, she strained to close her hand because once she did, the comet would be destroyed, and she started bleeding from various parts of her body. Eventually, the comet broke into small pieces.
People there: Look, she's shattering the comet.
People of Aoyama: Isn't she Austin's daughter whom they expelled? Looks like she's even stronger now than before.
As Hana lost consciousness due to the lack of aura, her father's hand didn't come to save her, but Ava arrived first, accompanied by the Zodiacs and Hana's friends from Aoyama.
Ava: What you did was amazing, Hana.
Raya: Goodbye.
Raya copied Hana's psychic ability and stopped the remaining small comets, returning them to their origin. However, her abilities were limited because her aura was gone.
Then Nolan suddenly appeared and use his Spatial ability and the remaining comet that shattered into pieces was go inside the Spatial ability of Nolan. 
Raya: It's done. 
Hana: Is it over?
Ava: Yes, it's over; you saved your loved ones.
Harry and Lisa, along with Hana's relatives, were astonished by Hana's display of power.
Lorelei: It seems you're stronger now, Hana, and I can't catch up with you anymore.
Hana: Hehe, not like that.
Austin rushed towards Hana.
Austin: Are you alright, Hana?
Hana: Yes, I'm fine.
Austin hugged her, and tears welled up in his eyes.
Austin: My child, forgive me for casting you out of this town, forgive your father for being blind to the truth.
Harry: What? Is Austin crying?
Lisa: How could this be? How did she become so strong? It's impossible.
Austin: Come back, my child.
Hana: I have a question for you.
Austin: What is it, my child?
Hana: When did you ever call me your child?
Austin was surprised by Hana's question and was almost speechless.
Austin: Didn't I always? Come back to us, my child.
Hana: You know, I never considered you as my family, not even Mother, because you let your child die at the age of four. What kind of parents would do that to their child?
Austin realized his mistakes with his daughter.
Chief: She's right, Austin. You never considered Hana as your child, and you even asked for my permission to expel your own daughter. I couldn't do anything but respect your decision because she's your child, and now you want your daughter, whom you once rejected, to come back? You're lower than low, if you know that. And the one you call a disgrace to our family? She's the one who saved us all. What about you? Harry and Lisa? Weren't you always making fun of Hana? Where are...
Hana: That's enough, Chief. I've returned here once, but you still rejected me, and let me tell you, Father, I never considered you as a family, and my family is only the Scorpios, remember that. Let's go.
And Hana left, leaving Austin to regret his actions towards his daughter.
Fienny: What are you? She already came back here once, and you still didn't accept her. And now you're moping around here. You're lower than low.
Hera: Is she my sister? She's beautiful and talented, Father. I thought my sister was weak? Turns out, she's strong.
Meanwhile, with Hana...
Ava: Are you sure about your decision?
Hana: Yes, and besides, you're my only family. Sister...
Ava: You've grown strong, Hana. I'm proud of you.
Hana: Thank you.
One month later, after their battle with the Twilight Predators, Aika visited Kill's grave.
Aika: Kill, you know, I've become stronger, and maybe I could now defeat those who killed you, but that's not enough. I need to become stronger and ask for forgiveness from Conrad and Emily for what they did, and mend our friendship. Kill, just wait a little longer for me to avenge you. Okay, I'm leaving now. Goodbye.
Another month passed, and Aika and Leonardo's meetings became more frequent, leaving Aika's friends wondering about the nature of their relationship. Emma approached Aika to discuss it.
Emma: Aika, you and Leonardo seem to be spending a lot of time together. Are you two dating?
Aika: I don't even know what I feel for him.
Emma: If that's the case, then you must have feelings for him too, right? I thought you loved Kill?
Aika: Yes, but Kill is no longer here. I don't know what to say to Leonardo because of what I feel.
Emma: Don't deceive yourself anymore; tell him what you really feel.
Aika: Okay, I'll think about it.
The next day...
Leonardo: Can we talk on the rooftop later? There's something I want to tell you.
Aika: Sure, I'll see you there.
Hours later, they met on the rooftop.
Aika: What did you want to say?
Leonardo: I've been feeling this for a long time, Aika.
Aika: What do you mean?
Leonardo: I like you, Aika, for a long time now.
They didn't realize someone was listening behind the wall.
Aika: I've been wondering what I feel for you too, and it seems like I also like you.
The listener was shocked by what he heard and started crying silently before leaving.
Leonardo: Really? Do you like me too?
Aika: But, this can't happen...
Leonardo: But why?
Aika: I shouldn't be feeling this for you because I should only love Kill.
Leonardo: But Kill is dead.
Aika: Even so, I promised myself that I would only love Kill. So if you can, Leonardo, please don't come near me for now.
Leonardo: Alright, I won't force you. I'll respect your decision. Thank you for everything. But if it's okay, can we still be friends when you no longer have feelings for me?
Aika: Okay.
And they both left the rooftop.
Emma: What did he say to you?
Aika: He said he likes me.
Emma: I hope you told him how you feel too.
Aika: I did, but I rejected him because I promised myself to only love Kill, even though he's gone.
Emma: Is that so? In that case, let's go; classes are about to start.
