Futago to Sensei

Ruri Ariya and Midori Ariya are twin high school students known as the Ariya Brothers. They have a pair of fine eyebrows and frighteningly similar appearances. A classics teacher, Kaoru Usami, was able to recognise them. When Usami sees the twins in a certain light, he releases his own inner greed. There is a special relationship between the three of them.
