Unlike his previous trips, the journey through the void this time was a lot more stable due to the countermeasures that he'd prepared, 'This is my fourth time going through this. I'd be ashamed if I still couldn't figure out how to travel safely even after having all of that data.'
Kisuke estimated that it wouldn't be too long until he's able to develop a stable pathway between the two worlds, 'But before that can happen, I first have to get Chaos' permission or take him out. I don't know which one is easier, though.'
When they arrived, Aika looked around with a puzzled face, "Where are we?", she asked after seeing the sci-fi-themed room. She thought that they went back to the tower, but she clearly remembered going through the void and she didn't recall a room like this within the tower she'd explored multiple times.
"Before I answer that, take this." Kisuke tossed her a small candy.
Although confused, Aika popped the candy into her mouth without a second thought, "What's this for?"
But before she could hear his answer, a massive headache attacked her consciousness and she almost fell to the floor from dizziness, "...W-what?" The confusion further clouded her mind as she tried to make sense of what was happening while holding her head in pain.
Before she completely lost consciousness, she heard Kisuke's voice echoing as it fades, "Slowly but surely, it'll all return to you... Until then, enjoy your life and I'll wait for your decision..."
Aika tried to fight back the drowsiness and struggled to open her eyes, "...N-no....." But as much as she wanted, she couldn't resist the call of darkness.
Kisuke caught her and carried her towards one of the rooms of the facility before he went out to prepare the rest of Aika's normal life, "Let's see... Explaining it to her parents, creating a backstory for the lost memories, and enrolling as a third year. I guess that should do it."
Leaving the Mars facility that was built by automated bots through teleportation, Kisuke returned back to Earth with an urgent goal of meeting Aika's parents and accepting their wrath.

In a normal house in the corner of Kuoh town, Kisuke was facing the Kiryuu couple in the living room. After the people of the supernatural world investigated them due to their interest in their daughter and finding out that they have nothing to do with their world aside from Aika possessing a 'failed' Sacred Gear, the couple were left alone.
Of course, that didn't mean that someone who had no pride wouldn't take advantage of their relationship with Aika to lure her out, so extensive security from the shadows was arranged by the Belial House and Grigori for their safety.
Sitting in front of him was a middle-aged man with a large build, tanned skin, short black hair, and black eyes looking sternly at him, expressing wrath and discontent. He was Aika's father, Kiryuu Haruto.
Aika's mother, on the other hand, had a very mature build, light skin, straight long brunette hair, and golden eyes which her daughter had inherited. From the kitchen, she asked, "Is barley tea fine?"
Contrary to her husband, Kiryuu Honoka had a gentle smile plastered on her face, but Kisuke could feel similar emotions hiding behind that smile as her husband's. In fact, it was much more intense than Haruto's, only it was contained.
Kisuke nodded while keeping his hat to the side, "That would be fine. Much appreciated."
For the next minute, only Honoka's steps and the sound of cold barley tea trickling were heard for a minute or two.
"Thank you." Kisuke expressed his gratitude and was about to take a sip on the offered drink when the father suddenly stopped him from reaching out to it, "Wait for a moment."
"Yes?" Kisuke looked up and saw a fist bearing down his face. Of course, the moment Haruto had these intentions, Kisuke already detected it as they are only normal people. To him, Haruto's fist moved at a snail's pace, but he didn't do anything about it and just waited for it to reach his face while relaxing all of his defenses.
The fist landed and Kisuke tilted his head to the side to avoid breaking the man's fist.
"Honey!" Honoka immediately reprimanded her husband.
But Haruto ignored her and took his fist back. Seeing that he couldn't even leave a mark despite dislocating his fingers, because it felt like he'd hit a concrete wall, he could only sigh, "I already heard about you and what you can do from your mother, but to think I can't even scratch you..."
Kisuke slowly turned his head back and replied, "You can continue hitting me and I won't say anything if that's a way that I can placate you. But I highly suggest against it, because you won't be doing any harm to me."
"Then what do you suggest we do to you?" Haruto asked while Honoka sat beside him.
Kisuke became silent for a few moments. Strangely enough for him, he couldn't seem to find the right words for this occasion. He could try explaining himself but that only felt like running away from his responsibilities so he refused to do so, "...There's actually nothing. I can only apologize for all the things that have transpired."
Bowing his head, he continued, "I ask for your forgiveness."
