After bidding farewell to the Princess of Hell, Saruto used his teleportation abilities while in his chariot and traveled to the Kingdom of Stars. There, the sky was entirely different… a vast horizon bathed in shimmering blue light, and a heaven studded with thousands of stars that glittered like jewels. The palaces were transparent, as if made of crystal, and the earth was illuminated by a soft celestial light, similar to moonlight, but clearer and more beautiful.
At the palace gates, Princess Star greeted him with a gentle smile, wearing a dress that shimmered as if woven from the breath of galaxies. She extended her hand, saying,
"Saruto… I am so glad you accepted my invitation. I wanted to show you something special from my kingdom."
But Saruto smiled, saying,
"I am delighted to meet you, my princess, and I look forward to seeing this thing you speak of."
Then he stepped out of the carriage and entered the palace with the princess. She led him to a vast, dark room, resembling a vast expanse filled with stars and suns. Saruto was amazed by the sight and said, "I've heard about these rooms in a book I read, and I never imagined I'd actually enter one. Thank you, Star, for giving me this opportunity." She replied, "No need to thank me, Saruto. It's my duty to you, as you are now our guest."
She continued, "Saruto, I need your help to create a black hole from your dark energy. Will you help me?" Saruto agreed.
She then began to explain the workings of a black hole and how it forms. Saruto memorized everything the princess said, and they began to put the theory into practice.
The princess formed two stars and began spinning them rapidly around each other. Then, Saruto created darkness around them to absorb their energy, thus forming a black hole. The princess was overjoyed and thanked Saruto for his help. In an instant, the black hole spiraled out of control and began expanding, pulling both the princess and Saruto towards it.
Saruto quickly formed his two swords. He planted one in the ground to stabilize himself and concealed the other, leaving the chain behind. He then held the princess's hand to protect her from being swallowed by the black hole.
Star apologized to Saruto, saying, "This is all my fault. I've gotten you into this mess, Saruto." Saruto reassured her, saying, "I'll solve this problem, so don't worry." He made her hold his sword, which was still embedded in the ground, and then he plunged into the black hole.
The princess cried out to Saruto, weeping for him as he entered the black hole, saying, "It's impossible for anyone to escape its gravity."
Inside the black hole, we see Saruto standing defiant against the immense gravity, saying, "This gravity is nothing compared to the gravity I trained for in the Time Chamber." He releases his energy and begins to recall what Star told him about how black holes form. He starts generating dark energy, attempting to absorb the black hole.
Outside, the princess begins to notice that the black hole is gradually shrinking and its gravitational pull is weakening. We see Yaruto absorb the entire black hole with the energy of darkness, leaving only a small remnant. He gives it to the princess, saying, "We made the remnant, congratulations, Star..."
As he speaks, the princess hugs him, weeping, and says, "You fool! I was so worried about you. Don't be so reckless again!" He hugs her back and reassures her that he won't worry her again. They leave the rooms as night falls and wander through the palace. Yaruto begins to talk about everything he knows about astronomy, trying to calm the princess a little. He succeeds in getting her to talk, and they continue talking until they reach the palace garden. They sit on a bench, and, exhausted from his journey through the realm of hell, Yaruto falls asleep with his head in Star's lap. She watches him as he sleeps, smiling.
Morning arrives, and before he leaves, the princess says to him with a smile, "Stay a little longer. Let's have breakfast before you go." Saruto agreed, and they sat on a high balcony overlooking the Kingdom of Stars, enjoying a light meal in the last moments of night before dawn.
After they finished breakfast, the princess stood and said, "I hope you will return one day to see my kingdom and not be gone too long."
Saruto smiled as he prepared to leave and said, "I will return… that's a promise."
In an instant, he vanished from her sight and reappeared in his carriage, heading towards the final invitation… the Kingdom of Light.
