She had been doing her best to keep them at bay. If she really wanted to hurt them she would have used much more aggresive tactics but it was bad enough that they probably already assumed she was a murderer so hurting more people wasn't going to help her case. Then seemingly out of nowhere a giant of a man emerges from the crowd and spoke with a very demamding tone. Maki stood ready, unsure of what the giant might do. She recognized him calling her by name. It was a bit annoying to be called by her first name by someone she barely knew but it was common here so she couldn't really be angry. Despite his inadvertant rudeness he seemed to be trying to help and even handed her some bandages before having the hostile students carted away. 

He made it clear that his name was 'Ro' and she repeated, "Ro-san." Ro-san also pointed out that the hostile students were called something a bit more difficult to repeat, "Asuhoruzu?" Regardless of whatever that meant, Ro-san had effectively saved from a bad situation. A few other students tried to speak up but Ro-san quickly shut them up as well. While she and Ro-san had a few classes together she rarely ever spoke to anyone other than Hana but she was glad to have someone looking out for her. 

The crowd had started to disperse, meaning that the worst of it was over. Maki, still in her bloody clothes, was desperate for a shower at this point. All she wanted was to rinse off the gore and change her clothes yet she had been caught up in a mess. Her own smell was starting to get to her. She had never felt so filthy in her life, even after hours of training she didn't feel anything like this. Looking at her own hands, stained with blood as they were, she could understand why they considered her a threat. Ro-san was her only ally at this point so she was wanted to make sure he knew it. Just as she was coming out of her thoughts Ro-san turned to her again and held out his hand. Of course Maki knew what a handshake was but she had never been comfortable doing it. Despite that she reached for his hand. Just as she was about to take his hand the sight of her own bloodstained hand caught her attention. It made her hesitate and instead she drew her hand back and bowed to Ro-san. "Sankyu belli machu!"
