Suruga Shushu
You can not ignore Suruga Shushu if you are diving into the spicy world of Mato Seihei no Slave. As a frontline fighter for the 7th Anti-Demon Squadron, she brings a lot of fun to the series. She quickly becomes one of Yuuki's main love interests. Shushu is different because she does not beat around the bush. She does not act like a shy girl; instead, she goes after what she wants with a big smile. In a cast full of serious monster fighters, her bold confidence is very refreshing.
Shushu is a knockout in every way, with an athletic tomboy charm. She has short blonde hair styled in cute twin buns, bright red eyes, and a heavily changed combat uniform that does not leave much to the imagination. But we have to be completely honest about how much she appeals to fans. She can grow to be very big or very small because of her special power. This naturally leads to some very provocative situations in her reward scenes with Yuuki. Fans love her because she is the perfect mix of an energetic genki girl waifu and top-notch ecchi. She acts like a tough, teasing senpai, but when things get serious, she turns into a big mush.
Shushu is the queen of fanart because of her special powers. Her wallpaper galleries are full of beautiful ecchi pictures with fun giantess points of view and very creative camera angles. You will find a lot of sexy art that shows off her amazing athletic curves in her ripped combat gear. Shushu artwork always hits the right spot, whether you want a cool action shot of her stomping demons or a dangerously sexy fanservice background for your phone.
