The entire day, Osomatsu had felt off. He should have been happy for his brother Choromatsu and that he was moving out, but something felt wrong. Oso knew this was not supposed to happen with everything inside him. The mix of emotion had made him sick to the core. He felt like he was starving, even though that was normal for him, being the pig that he is, it still hurt like hell. His head spun like crazy. Everything just made him feel sick. Osomatsu knew getting very upset or stressed could upset your stomach, but he never expected anything like this. And that had only been in the morning.

(Time skip, after most of episode 24. When Karamatsu drags Osomatsu outside.)

"Osomatsu, what the fuck where you thinking?" The words stung Oso's ears as Kara yelled at him. Osomatsu stood there. Nothing. All that he did was avoid eye contact as his breathing got heavier. It became a challenge to breathe. Karamatsu looked concerned. "B-Buraza... Are you okay?" And just like that, Osomatsu had started to melt. Shakily raising a hand to his cheek to feel what was happening to him. His entire body shook as he started coughing and hacking. "Osomatsu, please, Are you okay!?" Karamatsu's voice was muffled as Osomatsu started to cry, he could see Kara was crying, too. "N-... o..." Oso's voice came out raspy as he struggled to hold up his own weight. Karamatsu had lifted Osomatsu on his back and ran into the house. He had set Oso down on the floor, trying to keep him together. The melting started to get faster and faster. Karamatsu panicked. "It... It's o-.. kay..." Osomatsu tried to help. Karamatsu was sobbing extremely hard. "N-No it's not!" Karamatsu tried to keep his older brother together, finding out that it was a lost cause. He tries to turn away from his brother and forget what was happening. There's no way he could help. All Kara does, though, is cry. His sobs stopped as he felt himself being grabbed from behind. It was Osomatsu, trying to comfort him. "sor...ry.." The word made Kara's heart stop for a moment. All that could be heard is the two brothers choking on their own breath. Kara just sat there, not knowing what to do. After a minute, Kara tried to move away so He could look at his brother again. But then it hit him like a bullet. Osomatsu had melted onto him. He could feel himself starting to melt away just like his brother. He tried to call out for one of the other brothers. No noise came out of his mouth other than a whimper. But in an instance, Jyushimatsu was in the room.

Jyushi's normal large smile had twisted and turned into a horrified frown. "Nii-san? W... What happened?" The yellow matsu stood there in shock. Jyushimatsu dashed over to the pile of neet in front of him and tried to hold them together. No matter how much Oso and Kara tried to object, Jyushi held on tight. He could see his brothers had started to melt into him. Jyushimatsu's smile made a faint return. Jyushimatsu started to sob, knowing there is no way out now. At least he knew he'd be with his brothers.

The remaining three brothers ran into the room, once hearing the fifth brother's cries. Choromatsu let out a girly shriek as Jyushimatsu held onto Oso and Kara. Ichimatsu had immediately ran over to help Jyushi, Choro and Totty following shortly after. "N..o" "Pl-ea...se" "S-sto..p" These words kept repeating. The 3rd, 4th, and 6th brother kept trying to help the giant mass that was their brothers. When the three realized they were too hard to keep together, it was too late. They were already together.

The pile of matsus tried to prop itself up on it's arms. No success. Low moans and grumbles were the only thing that filled the house. Other than that, the entire place was silent. All six brothers were trying to help each other navigate in this new "form" they were stuck in. Arms and legs tried to move in all sorts of directions. The six eventually gave up on going their own way, all deciding to attempt to stand on their now four legs. Six arms pushed on the floor, helping the giant matsu up. They had knocked over some things, but still succeeded. Matsuzo and Matsuyo came in to see what was happening. Little did they expect to see their children as one malformed beast.
