In the Soul Society…
It was a star-filled night as Wonderweiss in a soul reaper uniform was gobbling down his meal with content.
His two fathers chuckled at the sight of the Hollow eating a giant bowl of Raman. He could probably give Yoruichi a run for her money if they had an eating competition. Though it has been a struggle, especially since many of the Soul Reaper did not like the idea of an Arrancar, especially an Arrancar that nearly annihilated the Head Captain and took his arm living among them, Wonderweiss has been settling in just fine.
They take turns of who looks after Wonderweiss at their houses for the week.
The cute child-like creature seems to be making friends with the other captains and even help against other hollows. Appointments with Kisuke have shown good results of changing the boy from a weapon to a being that could think for himself. Though he will never be what other people think is normal, Wonderweiss will be fine and was intelligent in his own unique way that was beneficial. Wonderweiss sees the world in a different way than others and was the best judge of character, which was surprising since he himself being a creation of Aizen.
"He's been doing really well in learning words of late. He's still not there in forming complete sentences but that's still a big step yet. He learned a new word today and is able to say it." Hisagi explained to the captain.
"Is that so? Wonderweiss, can you tell me the new word you learned?" The werewolf asked the hollow who stopped eating.
"Awwuuh?" Wonderweiss squeaked at his caretaker.
"Come one, Wonderweiss. I know you can do it. Tell Captain Komamura your new word." Hisagi encouraged the hollow.
Wonderweiss paused for a moment a slightly stuttered, "A-apple."
"Good boy, Wonderweiss! Good job. You're learning so quickly and so well." Komamura praised the boy as he ruffled his hair.
Wonderweiss made a cheering noise as both his guardians laughed.
After Hisagi said goodnight and returned home, Wonderweiss was taken to bed to sleep with his bug plushy and Komamura stayed up for the night to talk with the photo of his late friend, Kaname Tōsen.
"Kaname, he's developing so well. I can see why you doted him so much. Despite the blackened world, you were subjected to, he was your one little light, a son that was not spawned from your blood. He was the one thing you loved, and it became our duty to protect what you loved." He told the photo, "You would be so proud of how far he's come. I know you would have been."
In Wonderweiss's bedroom…
The little Hollow boy slept peacefully as he cuddled with the plushy.
He made noises in his sleep as a shadow loomed before him. It was familiar and at the same, it was something not.
"Awuuh?" Wonderweiss moaned as he looked to his window and felt a familiar spiritual pressure.
He then made a noise of happiness and crawled out of his window to follow. As he reached that person, he noticed that someone else was with him… someone new… someone dark.
"So, this is the Arrancar I have heard about?" The stranger questioned the other.
"Yeah, the little monster that managed to take down Ryūjin Jakka. My worm of a master and the other one are very fond of him. Do we see him as a threat?" The other person wondered as Wonderweiss realized it was not his friend, but someone like him, who share his powers.
"Does he still wield the same power?"
"From what I have heard, no. Since his treatments with the former captain, Kisuke Urahara, he no longer wields that power and has begun to change. I don't know what he can do now."
They then stopped talking as they notice Wonderweiss approached in his pajamas.
"Awuuh…?" The hollow tilted his head to one side.
"You are quite an interesting little creature. Never in my wildest dreams to see Soul Reaper take in Hollows. They have fallen low." The stranger commented as he noticed that sword on his back.
"Hmmm… I have heard tell of an Arrancar's power is called the Resurrección. Quite similar to a true Zanpakutō's power. I wonder if your Resurrección can be… reasoned with." The stranger smirked as he activated his powers.
It was then that Wonderweiss saw into his spiritual pressure clearly. This power was evil, and its energy source came from…
The stranger gasped himself as he took a step back from the hollow.
"Sir?"
"No, no this is serious. He's a threat to us all. We must leave now."
"What?" The other questioned.
"We must leave now! We cannot allow him to touch us or-."
"Baaaad…." Wonderweiss spoke as he caught their attention, "Sad, bad, mad…"
"What? What did you say?" The stranger demanded as he took another step back from the Arrancar.
"Sad, bad, mad!"
Then Wonderweiss attacks with a Bala!
In Captain Komamura's house…
He continues his talk with the photo of his fallen comrade as it eases the grief of losing him forever.
"The boy loves that toy, the one shaped like your Resurrección. He can't go to sleep without it. He misses you dearly. Hisagi misses you dearly. I miss you dearly. I wish you knew how many people loved you back then. I wish things were different." Komamura sighed as he wiped the tears from his eyes.
Then, he suddenly felt a massive spiritual pressure!
"What on Earth?!" The werewolf gasped as he soon heard someone banging on his door, it was one of his soul reaper cadets, "What's going on?"
"Sir, the Arrancar, Wonderweiss Margela has been spotted attack two unidentified intruders and is believed to be chasing them!" He explained.
"Wonderweiss… Find him, follow him, make sure the intruders do not hurt him." Komamura ordered as he left his home to find his adoptive son.
Near the edge of the 7th Division…
The stranger and the other were forced to flee as Wonderweiss was hot on their trail, repeating the same words over and over again!
"Sad, bad, mad!"
"Got to hand it to this kid, he would be a lot better master than Hisagi."
"We must depart and warn the others of this… thing."
The two then vanished before Wonderweiss was able to catch them.
With no sense of spiritual pressure and no clue where they were, he began to use his Vagido to alert the other Soul Reapers.
The Seventh Division soon came running as they found the hollow alone. Wonderweiss soon stopped as he saw adoptive father. Sajin Komamura came barreling towards him, hugging the child in relief.
"Thank goodness, Wonderweiss, are you okay?" The captain asked the child, who he noticed was growling and not looking at him at the moment.
Komamura then looked where Wonderweiss was looking and saw nothing. It must be where the intruders disappeared.
"Sad, bad, mad." He growled as he got their attention, causing Komamura to look down at him.
The werewolf has learned by being with his adoptive son that his words have great meaning. But this child was trying to say to him was a mystery.
"What's that suppose to mean?" One of the Soul Reapers wondered as they were confused by the child's short words.
"I will speak to the Head Captain in the morning. Until then remained on guard for the intruders. I'm taking Wonderweiss back home. It's passed his bedtime." Komamure announced as he gave the growling hollow his bedtime plushy, which calmed him down and made him sleepy.
Then he picked him up in his arms, causing him to nod off.
If Wonderweiss sensed a great peril, then it was important to understand what he's trying to say.
