Cartoonlover2016: I am glad that you are loving this story (including the last chapter) so much, but unfortunately, all things must come to an end. But at least this story will have a happy end right? In any case, here is the next chapter!

I don't own TMNT and only Koumori partly.

Usagi was not one to cry easily, but just like during Leonardo and Michelangelo's reunion, the rabbit samurai felt tears build up in his eyes. While Usagi did manage not to cry at the heartwarming scene, he did have a very big and happy smile. Michelangelo-san is back with his brothers…just like he should be.

"Hey, what about me?!" cried Raphael like he was pretending to be offended.

"Oh, I love you too Raph," laughed Michelangelo as more tears of joy left his eyes.

"Hmm…that's better," said Raphael softly as he gave Michelangelo a nuggie, making his little brother laughed even more as he tried to get Raphael to stop. Usagi couldn't help but chuckle himself as he saw Raphael's obvious display of love and affection.

"Okay that's it, I can't wait anymore! I'm jumping in! Mikey!" proclaimed Casey before he ran and jumped on the three brothers and hugged Michelangelo.

"Casey!" cried Michelangelo as he freed his arms and wrapped it around Casey. "How are you doing bro?"

"Oh you know, kicking bad guys' butts and keeping an eye on everyone. Same ole same ole," answered Casey cheerfully. "Though…it definitely wasn't the same without our pizza-and-Crognard-loving turtle. I'm…really, really glad you're back."

"Me too dude," replied Michelangelo. "Me too." Still smiling, Usagi glanced sideways to see that Leonardo and April were looking at the scene, tears in their eyes and with wide joyful grins. Koumori was still being held tightly in April's arms and he was also looking at the scene with a sincere smile while snuggling against April.

"Well, I think it's time that we tell you guys how Mikey was able to come back to us," said Leonardo as he went to the group hug and put his arms around them. Usagi's smile then lowered a bit, feeling apprehensive for what was going to come. Leonardo-san…do you have to tell them now? I mean, I know they should know what Michelangelo-san has been doing these last two weeks but still…

"While I do very much want to know that, there is something I want to know first," stated Raphael. Then before Leonardo could respond, Raphael took a deep breath and let it out. "Who is the rabbit mutant?!"

"Yeah, and why haven't we punish him yet for hitting April like that?!" added Casey. Usagi gulped as his apprehension was replaced with guilt.

"And calling her a wench!" pointed out Donatello. Usagi winced like Donatello had slapped him across the face. Trust me Donatello-san, I did not want to do that but I was afraid that if I didn't, Agent Bishop would suspect something was up…and then our plan would have failed...

"Or did you guys already do that and we just didn't see it?" asked Raphael.

"Stop it you guys! This is Usagi and we wanted him to play the part of one of the guards!" defended April as she quickly put Koumori down and walked till she was mostly in front of Usagi. "And he did a good job! Really, I'm fine!"

"And besides, he's not a mutant! He's an alien like me!" Koumori pointed out as he changed into a bat and flew towards Usagi.

"Whaaaaat?!" exclaimed Raphael, Donatello, and Casey as Koumori landed on Usagi's shoulder.

"No time no see Koumori-san," Usagi said as he rubbed the top of Koumori's small head with two fingers. "I am glad to see that you are safe and alright."

"Thank you, me too! And…have you visited papa and mama recently?" asked Koumori.

"Yes, and both of them are fine," answered Usagi. "But they are extremely worried about you. And they miss you terribly." Then a clear expression that one can only call homesickness flashed across Koumori's face.

"I really do like it here…April is awesome and the turtles, Master Splinter, and Casey are cool but…I miss Papa and Mama too. I…I want to go home," admitted Koumori, longing in his red eyes. Fully sympathizing with him, Usagi gave him a comforting smile.

"Don't worry, I will take you there soon," promised Usagi. Which I can start doing now actually. Michelangelo-san is with his family again. I have fulfilled my promise. I…I don't need to stay any longer. Then to Usagi's surprise, his heart then felt a pang of pain and sadness. Usagi let himself wear a wry smile as he looked down at the rooftop beneath his feet. I am sure going to miss Michelangelo-san...and even…

"That will definitely be good, but I sure hope that you don't plan to leave right now," Leonardo suddenly said, breaking Usagi out of his thoughts. The rabbit samurai looked up to see that everyone was looking at him, with a grateful and expecting faces. Usagi's eyes widened when he realized that Michelangelo, Leonardo, and April must have told the others how he had helped Michelangelo get back to this world. Oh dear…here it comes…

"Yeah, leaving before Master Splinter could thank ya would just be plain disrespectful and rude," added Raphael with a smirk.

"And I wouldn't mind looking at your wounds and making sure that they are doing reasonably well," said Donatello, motioning his hand towards the bloodstains on Usagi's clothes.

"And from what we heard from Mikey, you guys have had a really long day," commented Casey with a you-cannot-dispute-what-I'm-saying-isn't-true smile. "So you need a good long rest before you start traveling again. Heck, all of us need a good long rest after today."

"And besides…I still haven't treated you to pizza gyoza yet," said Michelangelo hopefully, though Usagi did see a trace of worry in his blue eyes. Even though they didn't say their gratitude outright, Usagi could read it clearly in the subtext. And that was enough for his face grow slightly hot and his heart feel warm and fuzzy.

Usagi was half-tempted to hide his face again but since they didn't actually praise him, he managed to control himself. It wasn't that Usagi hated gratitude or praise, in fact he liked it just as much as the next person. But whenever someone put him on a pedestal like this and either call his deeds out or expressed their gratitude, he always felt so embarrassed that he wanted to hide. After all, it wasn't like he helped Michelangelo because he wanted praise and glory like the Ultimate Ninja. He just wanted to help his friend out. But it really does feel nice to be appreciated…and accepted.

"What do you think Koumori-san?" Usagi asked of the young bat on his shoulder. The bat responded immediately.

"I want to stay! Just for a little while! I do really want to see Mama and Papa again but I also want to see Master Splinter one more time and get to know Mikey better!" Usagi then smiled, having come to his decision.

"It would probably be wise to rest, it is pretty late out after all and our journey isn't that short," Usagi said. "And…I really am curious to know just what pizza gyoza is." As Michelangelo then cheered along with Koumori, Usagi couldn't stop smiling as his heart threatened to burst with happiness. Michelangelo-san is with his family again and I do not have to say goodbye right now. And…even though I am not a part of their family, they have not forgotten me or pushed me aside. What more can I ask for?

TMNT

Master Splinter sighed anxiously as he glanced at the clock for the millionth time. As he nervously tapped his fingers on his knees, he looked at their lair's entrance. The entrance that his sons, April, Casey, and Koumori had yet to walk through. Master Splinter bit his lip as he sat on the couch in the living room, too worried to even bother trying to mediate in the dojo.

Where are they? They should have found Koumori and brought him back ages ago. Are they just having a really hard time finding a little boy or…did Koumori did captured? Since I doubt Koumori was running away and he couldn't have gotten that far…it probably the latter. Which means that they are trying to rescue him. Master Splinter then sighed, his heart full of fear and worry. My sons…my family…please come back home safe and sound. If even one of you didn't come back like Michelangelo…I won't be able to…

"Master Splinter! Master Splinter!" Master Splinter picked his head up and saw a truly wonderful sight. The voice belonged to Koumori, and he was running towards him in his human form, a big wide grin on his face.

"Koumori!" exclaimed Sensei with relief as he quickly stood up and hurried towards Koumori. He held his arms out and Koumori leapt into them and hugged him tight. "Are you alright?"

"Yes, I'm alright," stated Koumori happily. However, before the anxiety and fear could leave Master Splinter's heart, he noticed something. The rest of his family weren't entering the lair. Master Splinter's heart immediately skipped a beat.

"Where are the others?" asked the mutant rat as he put Koumori back on the ground, trying desperately not to let the panic he felt into his voice.

"Oh, they're right behind me," answered Koumori. Just as Master Splinter let out a sigh of great relief, Koumori continued.

"They just wanted me to go ahead to tell you the happy news so you can be prepared when he comes." Master Splinter raised an eyebrow.

"What happy news? And prepared for who?" Koumori just grinned wider than Master Splinter could ever conceived possible. Who or what in the world…Then the alien shape-shifter breathed in deeply before letting it out.

"MIKEY'S BACK!" For a moment, Master Splinter couldn't think, feel, or move. He could only stare at the joyful little boy.

"What?" Master Splinter finally asked softly as his heart began to hope that despite all odds, he did hear Koumori correctly. That despite all odds, the words the boy spoke were true. Then he heard the voice he had been desperately longing to hear ever since two weeks ago.

"MASTER SPLINTEERR!" he heard his youngest and dear son cry as well as the sound that only feet on concrete could make. With a gasp, Master Splinter looked up and saw Michelangelo jumping over the turnstiles, a bright light in his baby blue eyes and an ecstatic grin on his freckled face. The beautiful sight made Master Splinter tremble with burden-lifting relief as he picked himself up. He's here…I did hear right…Michelangelo, my son…he is really back!

"MICHELANGELO!" Master Splinter cried, his heart and soul overwhelming with joy and euphoria as he rushed towards his son. Then before he knew it, Michelangelo was in his arms and Master Splinter was hugging him like he had never hugged before. I can't believe it...but it's true! My son is here and he really is alive!

"My son…my son…" murmured Master Splinter as happy tears flowed down his brown furry face like a waterfall. At the sound of more footsteps, Master Splinter looked up to see the rest of his family, as well as a rabbit in samurai attire (who was acting quite shyly) arrive at the entrance. Before he could wonder who the rabbit was, his wonderful and special son spoke.

"I love you Father." Master Splinter looked back down at his son, who was hugging him tightly and was also softly crying tears of joy. His son who was very much alive. His child who had obviously found a way back to Earth and to his brothers. And back to his Father.

"And I love you too my son," stated Master Splinter, the agony he had felt for two weeks finally leaving for good. He then gave the top of Michelangelo's head a light but loving kiss. "I love you more than you could ever know."

:) I love happy endings, don't you? Especially when things get tough because it just makes the ending so much sweeter and fulfilling. But don't worry, there is ONE more chapter after this. Kind of hard to believe huh? I sure do...In any case, please review and I will update sometime this week (like hopefully tomorrow or Wednesday. Don't hold me to that though. It's just a goal). Till then, I hope you have a good day/night as always!
