Gyaru is falling for him. We can either ship a harem route or a route where only Hiura wins. Because we damn well know the Gyaru stands no chance.
At best, she can be the legal wife cause Japan doesn't allow same sex marriage. But, in that situation, the only action she'll see is Midou ramming his cock balls deep into Hiura. Churning his insides and leaving him gaping so hard that Hiura's cute anus wouldn't shrink back down to regular size for months. All while Hiura's small cute cock is just leaking cum onto his body. She could record it too.
Either way, she's not winning no matter what.
Btw, Hiura's little side tail on page 10 looks very cute.
