I really hate these long titles.

Nishimura is a regular player of Legendary Age a popular net game, having been stung by rejection from an alleged female player for in-game marriage, he ends up marrying a cleric named Ako vowing to keep the real world and gaming separate, but when the guild master asks for an offline meet up, the players are revealed to be Nishimura's classmate, the class president and Ako all being girls, however Ako still treats Nishimura as her husband unable to really exit her game persona, a school club is formed with the mission to help Ako open up to real life.
This is an interesting one as it covers a subject that isn't often talked about, there are real life cases of shut-ins not being able to distinguish real life to gaming life often ending more tragically, you are left guessing quite often how bad Ako's case is, at one point you even believe she's a game character who enters the real world but there are many points where she does have a high degree of self awareness like her high level of FPS skill compared to the others, the anime isn't long enough to really explore this and fails to take advantage of it's gaming plotlines, we get baited a few times into thinking were about to have a common trope only to subvert it, despite being technically a harem, it doesn't act like one.
Dub is fine if very basic.
Also the art style makes it look like all the female cast wear lipstick.
Final Verdict: It doesn't really take advantage of it's setting but it's at least competent at writing characters.
