The Holy Mommy Archives (Updated)

Being an ever-growing compilation of all new Anime / Manga / Light Novel material with themes centered around mommies and MILFs, be them the protagonist's own mother, or an unrelated mother who nevertheless serves as a main heroine. Occasionally these series will merely have a mom among the main characters, yet their existence won't be the story's primary focus.

1) Tsuujou Kougeki Ga Zentai Kougeki Ni-Kai Kougeki Okaasan Suki Desu Ka? (AKA Okaa-San Online, the one who started the trend.)
2) Bouken Ni Tsuitekonaide Okaasan! (The one with the ungodly overpowered Dragon Goddess mommy, Karma Abyss.)
3) Moto Kizoku Reijou de Mikon no Haha Desuga, Musumetachi ga Kawaii Sugite Boukenshagyo mo Ku ni Narimasen (The one with the albino adventurer mom and her two daughters)
4) Amaama Mama Dragon to no Ichaicha Isekai Boukendan (The OTHER Dragon Mom series. Currently untranslated.)
5) Musuko ga Kawaikute Shikataganai Mazoku no Hahaoya (The one with a demon mother raising her young child. Actually wholesome and not lewd in the slightest.)
6) Maken no Daydreamer (Isekai where main character is adopted and raised by a succubus mother, who herself actually becomes sexually attracted to her foster child once he starts hitting puberty.)
7 Mamori Mama Wa O Yobi Janai No!? Isekai Musuko Hankoki (Another Overpowered Mom Isekai manga. Only partially translated into Spanish. Story seems to be developing towards the mother obtaining a "Son Harem" of sorts.)
8) Isekai One Turn Kill Nee-san (An Isekai Manga where a shota boy and his perverted brocon older sister end up in a fantasy world, and she is gifted with massively overpowered stats despite having no knowledge of Fantasy Settings and Videogames. Technically not a Mommy Series but I'm mentioning here since it's basically just Mamako with a sister instead)
9) Ookumo-Chan Flashback (The one manga where the son develops a crush on his mangaka mom because he gets visions of his dead father's memories of when he met her as a teenager.)
10) Musume Janakute Watashi Ga Suki Nano!? (Recently released novel about a college student who falls in love with his childhood friend's mother. Also has a manga adaptation.)
11) Kirei na Onee-san ni Yashina wa Retakunai Otokonoko Nante Iru no? (Recently released novel about a young man and his older, rich sugar mommy gf. Currently untranslated.)
12) Kimi no Okaasan wo Boku ni Kudasai! (Manga about a young man who's in love with a widowed single mother, and who is trying his best to win her affection despite a brutal initial rejection. The manga ended but the translations are behind.)
13) Choppiri Toshiue Demo Kanojo ni Shite Kuremasu ka? (A Light Novel about a 15 year old highschool student who falls in love with a 27 year old Office Lady, and the struggles they go along with their relationship. By the same author of Musume Janakute. Has a manga adaptation.)
14) Shingeki no Eroko-san (Another series about a highschool boy and a 27 year old woman, only in this she's not an Office Worker but a former NEET working on odd jobs. And she's also a massive pervert with a fetish for highschool boys who has a hard time holding off her delusions.)
15) Youkai Ame Onna Ni Yoru Kamigakushi (Short manga series about a youkai woman who takes pity on a suffering, neglected little boy and spirits him away to the youkai world to be her adopted child. Very cute and fluffy.)
16) Osananajimi no Mama ja Iya? (Manga where a boy's childhood friend takes it upon herself to become his "mother", roleplaying as a doting, loving, caring mom for him almost 24/7, which is frustrating as he wants to be in a real romantic relationship with her instead.)
17) Hahazuka-san wo ×× ni Shitai (Another manga with a very similar premise to Osananajimi no Mama, only in this one it's the boy's idea to have his sexy classmate dote on him like a mother, rather than her own.)
18) Minamoto-kun Monogatari (Long-running and completed manga series about a feminine-looking teenage boy that is scared of contact with women who one day has to move in with his aunt. As he lost his mother at a very young age, his aunt essentially filled the role in his life, and he has an Oedipus Complex towards her. The story focuses on the aunt's insane project to groom her shy nephew into an ideal man by having him end up in relationships with 14 different women all of whom share similarities with the different female characters of Genji Monogatari, with herself as the 14th and final heroine.)
19) Boy's Abyss (A darker, more psychological manga about a teenage boy who lives in a small and unremarkable countryside town, and who cannot ever leave it and achieve his dreams of graduating university and living in Tokyo because he has to support his small family. Throughout the series he ends up in relationships with various women who also want to escape from the town, with the desire to commit Double Suicide being a constant. One of these women is his own mother, which is the only reason this manga is here.)
20) Maseki Gurume: Mamono No Chikara O Tabeta Ore Wa Saikyou! (Isekai. Guy is reincarnated as the heir to a royal family in a steampunk-ish fantasy setting. His mother is one of the main characters and MC has a bit of a Mommy Complex for her, though it's not the focus of the story.)
