This month's release features more Hirai content! (Patreon)

In PAT v0.22 there's an interactive scene with Hirai, Emi and Shuji, new phone messages that take Hirai's relationship with the ladies even further than before and a bunch of new voice acting!

$10 tier patrons can get it here! 

(The content in the update is actually so consistently explicit that I specifically had to make a non-explicit picture just for this update, by the way...)
