Because her own spiritual power was too strong for Shido to absorb, she could only split it into spirit crystals. The spirit crystals just split off were not pure.
Therefore, over these thirty years, she had given spirit crystals to tens of thousands of girls, turning them into monsters to purify the spirit crystals for her.
Finally, after tens of thousands of girls were sacrificed, ten spirit crystals were purified. One of these ten had already given birth to a Spirit on its own, so she planned to give the remaining nine to nine girls to turn them into Spirits.
As long as Shido sealed ten Spirits, he would absorb the spiritual power of ten Spirits. At that time, Shido would become an immortal being.
Once Shido became immortal, she could harvest the spirit crystals of the ten Spirits, restoring her own immortality as well, allowing her to be with Shido forever.
The appearance of Illustrious made her feel that the plan might fail. For this reason, she couldn't allow Illustrious to continue living in this world and had to eliminate her as soon as possible... Heavens! A true god! Itsuka Shido looked shocked. He hadn't even introduced himself, yet this Silver-Haired Girl said his name and knew his sister's situation. It seemed the Silver-Haired Girl really was a Spirit from the legendary RPGs. She probably used precognitive magic to learn his name and his sister's situation. But then again, why would his sister be on an aerial battleship!
"Why would my sister be on an aerial battleship!"
"Ask your sister!" Illustrious flew up impatiently and quickly left Shido.
"Ask my sister? But I don't know how to go up and find her right now!" Watching Illustrious fly into the sky, Itsuka Shido was now one hundred percent certain she was an RPG Spirit. Shido wanted to keep asking, but Illustrious had long since flown out of sight.
Shido followed the direction Illustrious had flown. He hadn't finished his inquiries yet, so how could he just leave?
After running for a while, Shido finally saw the Silver-Haired Girl again. However, there was a black-haired girl beside her. This black-haired girl was dressed just like the Silver-Haired Girl. Could it be that the black-haired girl was also an RPG Spirit?
Yatogami Tohka raised her sword, her voice very cold. "Are you here to kill me too? Then I'll have to strike first and take you out."
"Wait, wait! I'm not here to kill you. Yatogami Tohka, have you forgotten me? I'm your older sister!" Illustrious spoke nonsense with a straight face.
"Yatogami Tohka? Is that my name? Have I lost my memory? I have a sister? I didn't just pop out of a rock?" Yatogami Tohka lowered demon king: sandalphon, her head full of confusion.
Taking advantage of the fact that Yatogami Tohka was a newly born Spirit who knew nothing, like an infant, Illustrious continued to bluff. "You and I are biological sisters. Because our parents didn't get along, we separated six years ago. You went with our mother, and she married a man named Yatogami Ichiro. Your name was changed from Hikari Tohka to Yatogami Tohka. I stayed with our father, who never married another woman because he always loved our mother. He wanted to reconcile but didn't expect her to be already married, and he finally died three years ago in depression."
"Then what happened to my mother and stepfather!" Illustrious's expression was sincere and her storytelling vivid; Yatogami Tohka believed her.
Illustrious sighed. "Your mother and stepfather passed away two years ago in a car accident. With no one else to rely on, we started living together."
Yatogami Tohka was very sad. "Wuwuwu... Mother and stepfather are both dead. Then what happened to us later?"
Illustrious continued her tall tale, "Because you were my only relative and I was yours, we had a very good relationship—so good it changed nature. You fell in love with me, and I fell in love with you. After I confessed to you once, we successfully became lovers."
"This kind of relationship, being both sisters and lovers, isn't accepted by society. People were always whispering about us, but we didn't separate because of it, because we truly love each other."
"Ah! We're lovers!" Tohka was surprised but didn't feel any repulsion. "Then why do I have amnesia now?"
Illustrious fabricated, "A year ago, while you and I were in bed getting ready to sleep, a black hole suddenly swallowed us up. When we woke up from our faint, we had arrived in this world. As soon as we arrived, we were suddenly attacked by a monster. Just as our lives were in danger, a Mosaic suddenly appeared. The Mosaic was very powerful and wiped out the monster in an instant, saving our lives."
"After Mosaic saved us, we were very grateful. Mosaic said we were cute and that we had the potential to become Spirits, so she gave us two spirit crystals. The power of the spirit crystal was so great that you couldn't handle it and became a Spirit who lost her memory, while I endured it, so I didn't lose mine."
"So that's why I lost my memory!" After learning what happened, Yatogami Tohka's eyes welled up as she looked at Illustrious. She put away her demon king: sandalphon and rushed toward Illustrious, throwing her arms around her once she reached her. "Sister! We're finally reunited."
Illustrious also put away her demon king: sandalphon and hugged Tohka with both hands. "In this past year, I've searched so hard for you! But today, we're finally together."
Tohka hugged Illustrious tightly and whispered, "I'm sorry, Sister, for making you worry. Don't worry! No one will ever be able to tear us apart again."
Listening to the story of these two sisters from the side, Itsuka Shido was deeply moved. "That's wonderful, the sisters are finally reunited!"
...In the command room of the aerial battleship Fraxinus, ten thousand meters in the sky, everyone except Kotori and Murasame Reine started crying, moved by the reunion of the two sisters.
"They're so pitiful; their parents actually left them."
"Even though Tohka has amnesia now, I think she'll remember eventually."
"It's too much for worldly people to judge these sisters for being together. Love has no limits; I support them being together."
Kotori took out a lollipop and said, "Sisters from another world, huh! No wonder their Astral Dresses are the same. Judging by the Mosaic Illustrious mentioned, that person must be the culprit behind turning humans into Spirits."
"The most troublesome part is that these sisters are actually lovers! It seems like the difficulty for Shido to conquer these two sisters will be quite high!"
Murasame Reine frowned. This Illustrious was lying; they weren't sisters. She was one hundred percent certain because Tohka wasn't human at all—she was a Spirit generated spontaneously from a spirit crystal, unlike other Spirits who were transformed from humans.
She wanted to tell everyone the truth but was afraid they would become suspicious of her.
