Imouto Imouto means "little sister". Imoutos are very young at heart, enjoying the simpler things in life. They often struggle to keep up with everybody else because they are slow thinkers and slow doers; they prefer to do things at their own pace. Naturally they are fostered heavily by their friends and family, struggling to do anything by themselves. They are very trusting people, but are prone to being crybabies. Imoutos would like to be more mature and responsible people, but for now they simply look up to others and try to move forward in this big scary world.
