There were also plenty of titles trading in pure unadulterated fanservice, although most of them were not quite as literal about this as this title.
SUPER HXEROES (Dokyu Hentai Eguzerosu), by Ryoma Kitada. First published in 2017 and first published in North America in 2021.
For some time now, the insectoid Kiseichuu have been ravaging the earth, trying to destroy humanity by sapping their lustful feelings. The only defense against them are the HXEROES team, a group of teens who can weaponize their youthful horniness into alien-busting attacks. Their leader is Retto Enjo, who is currently struggling to redefine his relationship to his prudish childhood best friend Hoshino Kirara. Then Hoshino discovers not only Retto's secret, but that her own power might exceed his own.
