Meeting Izumi Again

 At a private house, the Kitagawa twins went inside the bathroom and saw this person in the tub.

They actually knew this person, Izumi Kawahori, from when they attended elementary school.

The twins were completely attracted to their long time friend (skin and body).

But, what they were amazed to see is that Izumi had officially become a female.

So, Koichi and Takeru thought she looked gorgeous.

As it turns out, in the illustration, the twins are actually bisexual/pansexual, just like the Suzuki sisters.
