I remember this set from the raki-suta.com image board. Kagami and Konata get married and have little Kagami/Konatas. One has blue pigtails and a mole, and the other has a purple ahoge.
We're counting on you Mama-Konata!Hey... you two can't get all those today...But dear, aren't you the one who told the girls that if they brought their grades up, you'd buy these for them?
