Then I'll get some drinks...AhI've eaten dinner, so I guess I'll do homework...Ufufufu~Nii-san, can I do homework with you as well?Math IMath IIIYeah, that's fine.Rather than being your younger sister, I wish I was born as your twin.And I could protect Nii-san from all those insects and unnecessarily bare wolves.Twin? Why this again?Wait, about midway through the scariness jumped way up.Math IIIf we were twins, then I'd be in the same grade as Nii-san, and we could study the same things for tests, and during the breaks, we could cheerfully go to class together.Taa-kun! Onee-chan will do it with you!
