The dress which Laika is wearing is a dress Kawasumi Mai wears from PC game "Kanon". Why is she wearing a dress early in morning? That's because I just wanted to draw Laika with that dress (I really wanted to add rabbit ears too...). Or... could it be that she wanted to impress Onii-chan? Nah, I don't think so. More likely explanation is: Today's was 50th comic strip! Yeah, congratulations to me!!
