Well, is not so often that I make reviews of anime but I am going to try doing, small reviews for some animes... some I may love it, some I may hate it.
This one was a very straightforward anime. It never try to be a good isekai with new stuff or so. This is a ecchi anime supported by all those porn coming out of Japan. You know, a bit of porn with you mother ? (or mother in law). They really enjoy this... (and so do we, but we don't talk about it).
Enter Mamako Oosuki - that mother you always wanted to... but you will not have. This is a ecchi show so every episode our main character is thrown into something lewd without him wanting or knowing lol
Don't expect anything else because you won't have it. This is straightforward ecchi show in another world....
