Rantaro sighed as he watched the three fight each other. Whatever was going on was certainly interesting. Despite what had happened, Shuichi had little hesitation when he got back up and tried to help Kokichi fight Kaito. Rantaro would need to separate the three before things got much worse.
Being quick to act, he placed Shuichi back on the bed before pulling Kaito and Kokichi away from each other. He would need to make sure that none of them had been seriously injured, but they had definitely sustained injuries in the fight. Due to Kokichi's punch, Kaito's nose was heavily bleeding, possibly broken, and while he wasn't sure what Kokichi had done to himself in the process, he knew that he was in pain. As for Shuichi, he wasn't too sure, but he hoped that nothing happened to him.
"All three of you, wait here…and don't try to kill each other…" he sighed softly. "I'm gonna get a doctor so they can make sure none of you seriously hurt each other…or yourselves…"
After he spoke, he sighed softly and left the room. He was worried that the three would start fighting each other again, but he needed to make sure that none of them were horribly injured, that nothing needed to be treated, so he did need to get a doctor. All he could hope for was that none of them tried killing each other while he was gone.
