I want to see Izumi's heart skip a beat when Ninomiya lets his hair down or brushes it back.
About
The relationship between Ninomiya and Izumi Izumi is the mentor, and Ninomiya is the student. Ninomiya was the one who asked Izumi for instruction. Ninomiya originally learned bullet-firing techniques from Izumi. After learning from Izumi, he has improved immensely through his own talent and effort. Ninomiya holds Izumi in high regard. Despite his own strength, Ninomiya acknowledges Izumi's skill. Ninomiya properly bowed his head to ask Izumi for teaching. Instead of thinking "I'm strong, so I don't need to learn from others," he will seek instruction from anyone, even someone younger, if it is necessary.
