3 Items, after quite some time...

 

...Arrived this morning.
Good★Come 19, Hero Vision 40
and
Kimijima Asaya Style.
The last one comes with a DVD.
~~I don't expect it to be this small, though.~~

So...out of the 4 on the cover of Hero Vision 40,
Kimijima Asaya, the model guy, is the first one in OOO to have his solo PB. 
Not counting Miura Ryosuke's solo photobook before Ankh's time.
