Well, time for Apollo, Artemis and Rachel to save the realm of Thanatos. Enjoy
Through the Senkaimon, Apollo, Artemis and Rachel were at a door on Olympus with a screaming face. They entered and arrived in Death's Domain.
-In this realm of chaos, there are destroyed castles, walkways and environments. Apollo said, "A realm that was not ruled by us."
On the main path, they saw a woman with shredded clothes, messy long black hair and a Hollow mask. Artemis said, "Hecate, Goddess of Magic. I'll take this, brother. Bankai! Shuryo tsuki shimai!"
She had long light blue hair, light blue marks on her face, the light-blue Zanpaku-to, and a light blue dress.
"I shall finish this easily." She shot an arrow into the black sky and Hecate was frozen in a cylinder of ice and shattered.
Rachel said, "Fantastic. I'll take the next one."
"Sure."
-They walked to a rotunda and found a man collapsed on the ground. As they walked to him, they noticed that his hand was moving like an insane man, and a Hollow mask was slowly appearing on his face.
Rachel said, "Who is he?"
"Deimos, God of Fear."
"Gotcha."
Rachel's charm bracelet shined and she had her Hearts of Protection Keyblade. "Stop, Koruna."
Deimos was frozen in time and Rachel attacked him repeatedly. Then he died. "Apollo, you're next."
"Awesome."
-They arrived at the Palace of Thanatos, and they saw a woman with black wings and of course, a Hollow mask.
Apollo said, "My, my. It got Erinys, the Daughter of Thanatos. Oh, well. Bankai. Chi ni ueta hi buraza."
He had armor on his left shoulder, a quarter of a sun tattoo on his lower right stomach, red marks on his face and the harp-like bow.
"Just like the harp I had at home."
He played a quick tune and released all 361 arrows and it killed Erinys.
"This is all too easy. Artemis, we shall do this next battle together."
"Fine."
-Inside of the Thanatos Temple, they found Hollow Thanatos, personification of Death. They released their Bankai, combined the attacks and killed him.
-They returned to the Soul Society, told us what happened, and I said, "Terrific, Sun and Moon Gods and Rachel. Nick; you, Hades and Ares shall reclaim the Underworld next."
"Awesome."
Ok, I know that Erinys is from God of War: Ghost of Sparta and that she is one of the daughters of Thanatos, but you can kiss my ###. Stay tuned for the Underworld.
