“This can’t go on Princess! It’s scaring our children every night!” a pony mother complains to Celestia.
“Yes, we will get right on that... please be calm~”
“Princess, there has been another report of a Hollow attack in the forest, its victim was a young colt named Blaze Trail,” a guard says to the Princess, giving her more problems as it is.
Celestia orders the guards to announce the gates are closing and they will now attend to important matters, regarding the attacks of her subjects.
“Now you see how hard it is for me to contain such things, my dear sister,” Celestia says to Luna who is looking over the horizon from the window.
“I know, sister... But why must these creatures attack our pony folk... it doesn't make any sense!” Luna says, as she trots over to her sister.
“I don’t know myself, Luna. I thought when we defeated Aizen, those things would stop appearing, but it seems my guess was wrong for they kept on coming back!” Celestia sits on her throne, thinking of what to do next.
“You know sis, last year Ichigo came for a surprise visit... Saving two ponies in the process...” Luna says, as she sits right next to her.
“He did?” Celestia perks her ears up. “How did he ever return? I thought the gate was closed, right after he and the others went back!”
“I sent him back.” A familiar voice is heard. Both Luna and Celestia stand up, prepared to defend themselves, horn glowing and ready to blast anything.
“Hold on, you two,” Yoruichi walks out of the dark area of the room, revealing herself to the sisters.
“Miss Yoruichi?” Luna says in surprise, as she calms down removing her magic on her horn. Celestia did the same.
“However did you come back? Didn’t you leave with the others?” Celestia asks Yoruichi, who just gives a smile in response.
“Did you see me leave with the others?” Yoruichi asks them. Now that she mentions it... They had never actually seen her leave with Ichigo and the others.
“I’m guessing you remembered it now,” Yoruichi says, as the two sisters just nod.
“But what's the reason for you staying behind?” Luna asks her, which she already has an answer for...
“Remember when Ichigo first came here? He accidentally made an interdimensional gate, which brought him here in the first place... that gate disappeared on our world... but... the gate actually went to Hueco Mundo.” Yoruichi pauses for a reaction...
“What is Hueco Mundo?” Celestia asks in curiosity. Yoruichi had waited for this...
“Hueco Mundo is a place known to be the Hollows home, or where the Hollows were formed and born. Since Aizen was defeated along with the Espadas, that world just became independent, and kept making Hollows for every day. That gate is still opened, but only a small crack in it... small enough for some Hollows to squirm out and go to your world,” Yoruichi further explains. “Furthermore, I stayed behind because I was the one containing everything in order for those Hollows to not reach you, but because of a major infestation on the north side; I called Ichigo where he rescued those two ponies, but sent him back immediately after that for he had school that day,” Yoruichi finishes her explanation, leaving the two sisters' mouths wide open. “Oh, I forgot to mention,” Yoruichi says, as she further lengthens her explanation. “You are not dealing with ordinary Hollows by the way.”
“Then, what are we dealing with?” Luna asks.
“These are called Gillians." She looks out to the window then further explains. "Gillians, also known as Menos Grande... are a race of creatures which are born from Human souls who, for various reasons, do not cross over to Soul Society after their death and stay in the Human World for too long. They are corrupt spirits with supernatural powers that devour the souls of both living and deceased Humans. Hollows settle in Hueco Mundo, but can cross over to the Human World and Soul Society.
"Also, there’s the Adjuchas also known as Intermediate Great Hollow that are the second classification of Menos. They are smaller than Gillians and far fewer in number. However, they're much smarter and stronger than Gillians. They're often the ones who lead Gillians into battle. Adjuchas are commonly solitary creatures rarely joining into groups. They are powerful enough to challenge a captain of the 13th Court Guards.
"Lastly the Vasto Lorde or Highest Great Hollow, are the third classification of Menos and the highest level of evolution. They are extremely small Hollows, roughly the same size as humans and are extremely rare in number. It is said that you could count their entire number within Hueco Mundo with only the fingers of your hand. The Vasto Lordes' combat capabilities are above that of the captains of the 13th Court Guards. But, now, they found the way into your world,” Yoruichi says, ending her own definition of what she had found out through out her scouting and eliminating some of the hollows she'd encountered before.
“Wait, hold on... The last two you mentioned, from what I have heard, are rare to see, but why are they now in our world?” Celestia asks, making a good point...
“You see, from what I have seen and fought in my days in your world... That is what I have uncovered and learned so far...” Yoruichi says. “But... The last two I mentioned... are far more dangerous than that of a Gillian.”
Luna and Celestia’s mouths fall wide open for the second time...
“S-so, a-are we safe to assume that, you can take care of them alone?” Celestia asks, snapping out of her surprised state.
“I’m afraid that the outbreak is already imminent,” Yoruichi says, with a much more serious face.
“What do you mean?” Luna asks, becoming a bit worried.
“You see, the crack I mentioned earlier, became larger over the past year; the reason that I called Ichigo last time was to clear all Hollows in an area... but after a week, the conditions got worse. If this gate keeps on opening up, your world might need another Soul Society,” Yoruichi says.
Celestia and Luna look at each other, thinking of what to do next...
“What do you suggest, Yoruichi?” Celestia asks.
Yoruichi lets out a smile, then looks at them directly. “What else? But to call them back here...”
