Kishi Danchou wa Moto Megane Shoujo wo Hitorijime Shitai

I was caught up in a summoning ritual and pulled to another world. But I was treated as a nuisance, until Leon, the commander of the Second Knights Battalion, saved me. He was super strong and handsome! He was blunt but kind and always took care of me. But why does he get so nervous when I take off my glasses? Underneath the thick-rimmed glasses is a beautiful girl! The knight commander will fall in love and dote on her with all his might! (Source: Ichijinsha, translated)
