Go To

Do You Love Your Mom and Her Two-Hit Multi-Target Attacks? (Tsūjō Kōgeki ga Zentai Kōgeki de Ni-kai Kōgeki no Okā-san wa Suki desu ka?) is a fantasy Light Novel series written by Dachima Inaka and illustrated by Pochi Iida (of The Elder Sister-like One fame). It was serialized by Fujimi Fantasia Bunko from January 2017 to April 2020. This series earned a bit of huge hype due to a deliberately provocative plot and a parody of the current incestuous fashion in light novels. Ultimately, this led to the publishing house being able to sell the first two volumes in excess of 100,000 copies within a few months and win the Fantasia Grand Prize.

Masato Oosuki is a teenager who is embarrassed by his loving but smothering mother Mamako. One day, after filling out a survey, he gets transported to a fantasy world inside an online game and becomes excited that he's finally free of his mother and will get to be a cool hero. To his shock, Mamako gets transported to the world too and quickly overshadows him in skill and power. Masato has no choice but to travel with her.


A web manga adaptation was serialized in Young Ace Up from September 2017 to January 2021. Both the light novel and manga are licensed in North America by Yen Press and an Animated Adaptation aired from July 13 to September 28, 2019. An OVA episode was released on March 25, 2020. The trailer for the animated adaptation is available on YouTube.

This work contains examples of:

  • Affectionate Parody: Of the oversaturated isekai market as a whole, and the Incest Subtext that sometimes crops up in light novels. Masato is a Stock Light-Novel Hero given the chance to live out his fantasy of being a legendary hero who defeats the demon king with his harem of attractive adventurers, only to be undercut and thrown into sexually awkward situations at every turn by his overpowered, overly affectionate mother.

  • Always a Bigger Fish: In Episode 6, Masato and Medhi pursue a giant fish monster, but the fish gets caught and eaten by a giant sea anemone monster.
  • Amnesia Episode: In the OVA episode, Masato suffers from amnesia, which results in him losing his memory, including who his mother is. After he finally recovers, the episode ends with Mamako, Porta, Wise, and Medhi losing their memories.
  • Beach Episode: The OVA takes place at the beach.
  • Bleached Underpants: The character designs are provided by hentai mangaka Pochi Iida, famous for her supernatural slice of life series The Elder Sister-like One.
  • Censor Steam: Happens during the hot spring scene of Episode 3. Mamako gets most of it, as usual, while Wise initially opts for a Modesty Towel, but does receives some coverage after dropping it. The steam also covers mostly just the front, as when Wise flees from the bath her rear isn't censored.
  • Clothing Damage:
    • In the second episode, Mamako gets covered in clothing-destroying goo after a slime attacks the party. And the same attack knocked Masato on top of her and left him too slippery to move.
    • In the OVA, Masato's swimming trunks get shredded by Wise's wind attack. Later, a crab snips off Mamako's bikini.
  • Didn't Think This Through:
    • Sure, let's just make a portion of your playerbase grossly overpowered for shits and giggles, What Could Possibly Go Wrong? The answer is flagrant abuse of that power, along with judicious amounts of (illegal) Game Modding to bend the rules of the system and wreaking all kinds of havoc that not even system admins could do anything about, of course. Fortunately, there just happens to be another mom on the hero's side to even things out.
    • Granting grossly overpowered abilities to mothers in what would otherwise be any kid's greatest fantasy brought to life while denying those same kids such abilities? Virtually every child playing the game deeply resents this mechanic as it ruins a lot of the fun for many of them, to the point that a whole guild was spawned out of the plethora of players so they could play the game the way they originally intended to play it.
  • "Do It Yourself" Theme Tune: The ending theme is sung by Ai Kayano (Mamako).
  • Early Game Hell:
    • Masato faces this hurdle from the get-go, not because the game itself is hard, but because Mamako kept hogging all of his kills without effort due to her artificially inflated combat abilities. In fact, this is the case for most players who join alongside their mothers, as they start low, and have to worry about mundane grinding as well as keeping all of their grinds from being yoinked by their overpowered mothers. It's never explained whether or not non-combatant players like Porta have to contend with this, however.
    • This is taken to the extreme during the school event where Masato and Wise try to level themselves up. Despite already having hilariously bloated stats and not even directly participating in the event, Mamako is showered with XP by the teacher for even the most ridiculous answers and dominates the school festival without even trying to compete. And once it's all done, the only way Masato and Wise can get the gear they came to the school for in the first place is to spend their XP on a horribly rigged gacha wheel. After burning every point they earned, the two come away with an ocean of potions and only one real prize: an apron that only Mamako can equip, which Shirase implies shouldn't have even been in Masato's prize table.
  • Everyone Can See It: At the end of the first novel, Wise is allowed to stay because of her obvious attraction to Masato. When Shirase starts talking about it, Wise subconsciously starts touching the matching ring she shared with him.
  • Excuse Plot: Both the game and the story at large. The premise of the novel is that a government-funded organization created an MMORPG to promote familial bonding between moms and their children, and some players are selected to be beta testers, among them Masato and his mother. After being digitized into the game, the mom and son duo are tasked with improving their relationship if they're ever going to get out. Of course, given what the two leads are like, this could take a while.
  • Exotic Eye Designs: As per the art style, everyone has white pupils. It could just be light reflections but peculiarly always centered over where their pupils would be.
  • Faceless Masses: Zigzagged. While many generic NPCs don't have fully-rendered faces due to the game's Obvious Beta state, there are characters with full faces here and there, most notably important quest givers or functions (e.g. merchants, innkeepers, etc.).
  • Formula with a Twist: The series asks "What if The Hero was summoned into an RPG Mechanics 'Verse and was still outclassed by his own mother?"
  • Full-Frontal Assault: When a Slime destroys Mamako's clothes, she furiously kills it with her swords.
  • Fun with Acronyms: The game is called a MMMMMORPG, which stands for "Mom's Massively Maternal Multiplayer Making-up-with Offspring Role Playing Game".
  • Girl-on-Girl Is Hot: In episode 6, Shirase gives Mamako a hug, then unexpectedly starts rubbing all over her body and making her moan in order to take her measurements. Shirase asks Masato if this sight turns him on. He unconvincingly says it doesn't.
  • Hurricane of Puns: The settings, game mechanics, and character names are rife with mom puns.
  • Hyperactive Metabolism: Averted. When Wise runs out of mana at one point, Porta hands her a large amount of potions to consume and get her energy back. She becomes sick and totally stuffed after just a few drinks.
  • I'm Standing Right Here: Episode 6 of the anime has Masato openly fawning over Medhi while also comparing Medhi and Wise's figures. While standing right next to Wise. It doesn't end well for him.
  • Immunity Attrition: Medhimama uses a spell to make Medhi's classmates fall asleep. Masato isn't affected and explains his armor protects him from status effects. Medhimama simply turns up the power on her spell until it overrides his armor's protection.
  • Incest Subtext: The series parodies this kind of Fanservice. Masato clearly and repeatedly makes it clear how he is annoyed by the ambiguous moments with his mother, yet we can repeatedly see that he finds her sexually attractive. On the other hand, this also annoys him, and Mamako constantly frightens her son with her indiscreet behavior and unintentionally vulgar jokes. This is even recognized by Yen Press, calling this series as a "momcom roleplaying adventure" in its marketing materials. That said, he's horrified by seeing her in skimpy or fetishy clothes, to the point where he vomited blood in one instance.
  • Indirect Kiss: In the OVA, Porta tries to blow up an inner tube but runs out of breath, so Masato offers to do it. Wise jealously stops him because it would mean Masato and Porta's lips would indirectly touch.
  • Info Dump: Due to the novel's threadbare explanation of lore and game mechanics, it is often the job of Shirase or other NPCs to deliver exposition or explain the situations that are unfolding.
  • Inside a Computer System: Unlike most isekai works concerning MMORPGs, Masato and Mamako are just literally sucked into the game via Masato's computer monitor, leaving no physical body outside of the system.
  • Karma Houdini: Some of the more abusive parents such as Wise and Medhi's mother get off with hardly any punishment at all.
  • Kirk Summation: At the end of volume 3, Amante tries to break the party at the top of the tower. Masato then responds with a rousing speech that goes from acknowledging Amante's points to stating that the bizarre unknown of adventuring with one's mother, while odd, was a true adventure, boldly going where no RPG has gone before. This occurs in the last episode of the anime but in much abbreviated form.
  • Lap Pillow: Mamako offered her son this to make amends after he lashed out at her following her armor shopping binge.
  • Lens Flare Censor: Mamako's naughty bits are covered with bright light shafts when her clothes are disintegrated by a boss slime. As with Wise's Censor Steam, her butt isn't censored.
  • Limited Wardrobe: Zigzagged. While Masato, Porta, Medhi and Wise always have their combat gear equipped, Mamako and other moms notably have veritable stockpiles of cosmetics that they could change to at a whim.
  • Love at First Sight: Masato gets it bad for Medhi, though he dials it back a bit after seeing her dark side, and mostly gets over it not long after.
  • Long Title: As if the page name isn't obvious enough, the official English title is twelve words long. The title is so long that the licensed subs of the anime have to settle for the much shorter Okaa-san Online.
  • Marshmallow Hell: Mamako does this to Masato in Episode 3 after jumping into the hot spring with him... to block his vision so Porta and Wise can get in too without him seeing them naked. She does it to Masato again in Episode 6 while congratulating him on winning the pool challenge.
  • My Rules Are Not Your Rules: The MMORPG that the main cast are playing barely has any rules or guidelines as to what certain players can or cannot do. Balancing seems to be a foreign notion, as explained under Early Game Hell, Power Creep, and Unstable Equilibrium, but what's truly egregious about this is the fact that some (mom) players could outright do things they're not supposed to be able to do, up to and including casting spells without chanting, or creating game-breaking status buffs through cooking that makes a further joke of the game's mechanics.
  • Negated Moment of Awesome: In the first episode of the anime, when Masato is first transported inside the game world. Surrounded by otherworldy scenery and creatures, he proclaims his dream of being a heroic adventurer has finally come true as heroic music swells... until his mother transports in right next to him and scolds him for leaving her behind.
  • New Life in Another World Bonus:
    • Masato and Mamako both get to pick a powerful, high-level sword after the game's introduction. The twist on the usual formula is that while Masato picks a relatively weak sword, Mamako takes the two other swords, both of which give her a powerful multi-target attack (hence the title) capable of wiping out entire swarms of enemies at once.
    • Both Masato and Mamako's stat windows can be seen during their registration into the game. Mamako's strength stat exceeds 400 from the get-go, compared to Masato's 3. As other mothers are introduced, it is implied that all participating mothers in this game are given a perk that grants outstanding power.
  • No Name Given: Not the characters themselves, but the encompassing game they're all playing.
  • The Nudifier: Parodied when Masato and Mamako both get hit by a Slime's attacks. Mamako's clothes dissolve, while Masato gets confused why nothing is happening to his own clothes.
  • Obvious Beta: The unnamed MMORPG the main cast is playing is explicitly noted to still be in closed beta. As such, many of the core mechanics haven't been put into place, actual game content is threadbare, balancing is all but non-existent, and many of the generic NPCs don't even have proper faces.
  • Overly Long Gag: Mamako being the single most powerful entity in the game for no reason at all despite being entirely clueless about everything, and yet keeps getting showered with free stuff to make her even more broken.
  • Please Put Some Clothes On: Masato says this when Mamako's clothes are destroyed by a Slime. Porta gives her a Naked Apron, and Masato complains that just makes it worse.
  • Power Creep: Played for laughs thanks to the moms being Purposely Overpowered.
  • Power Perversion Potential: Invoked by multiple monsters on Mamako for fanservice, on the grounds that these things rarely happen in anime to a mom.
  • Purposely Overpowered: As part of a gag, all moms in the game are given incredibly inflated stats and hilariously broken powers compared to those of their children, with Mamako being the prime example. They are also not governed by the game's rules on things such as player-killing, using third-party softwares to cheat, attacking/abusing GMs and game important NPCs, or using CC spells on other players when not in combat, all of which are flagrantly displayed by Wise and Medhi's mothers.
  • Questioning Title?: Sounds like a joke at first, which is fitting for a parody, but by the end of the first volume, it seems it was actually a serious question for the main character, even excluding the Incest Subtext.
  • Random Events Plot: Unlike most isekai work, there is seemingly no large underlying plot to the story, nor are there any major arcs, with Masato and co. only finding new things to do by being directed by Shirase, or directly blundering into it.
  • Required Party Member: Played with. Due to the game's nature, players cannot enjoy it solo. They have to enter it along with their mothers on registration, and have to somehow improve their relationship standings if they are ever going to leave. It's zigzagged in that as a player, you're not strictly required to party with your mom, but unless you're on good terms with her, having her goofing around doing anything else would be a detriment to yourself since there will be no progress made, as was the case with Wise and her mother. On a side note, it's unclear if dads will get to play this game as well, as it's seemingly designed to only accommodate mom-and-child pairs.
  • Running Gag:
    • At least every dialogue between Mamako and her son will contain jokes about the worldview of the housewife and the hysteria of Masato.
    • Shirase almost always showing up injured and/or dead. Also, Shirase changing her name by making parts of it longer to say.
    • Mamako herself is a walking, talking trove of these, most if not all of which are guaranteed to happen at least once an episode:
      • Masato and co. struggling to fight a boss or other mothers, only for Mamako to trot onto the scene and defeat everything in a single blow.
      • Mamako receiving preferential treatment by every NPC ever, on top of getting showered with every single game bonus under the sun, and then some, just by virtue of being there.
  • Schmuck Bait: Masato and Wise are greeted with a quasi-gacha game after graduating from their special training class that they could spend their hard-earned SP to (maybe) get a good rare item. Like any other gacha, it only gave them HP and MP potions despite them dumping every single point into it. After wasting all his SPs, Masato gets one free spin and finally gets something nice, but to his woes it's an apron that only his mother could wear that's not even supposed to be in the prize pool in the first place.
  • Shout-Out: Lina Inverse makes a minimally-censored appearance in episode 2 when Masato is considering Wise's attitude.
  • Squishy Wizard: Wise and her mother are both Sages, which, like all Mage-types, rely on magic to do anything. So when the enemy hits them with a sealing skill, they are instantly crippled.
  • Stealth Parody: Of the overabundance of Brother–Sister Incest and Little Sister Heroines in light novels. In particular, the author intentionally uses clichéd phrases from such stories like "we are family, so it's normal" or "the connection between us as a mother and a child". It also pokes fun at the popular trend of isekai protagonists always being The Ace, with how Masato, while Genre Savvy, is a complete pushover compared to his mom, who's at least three decades too old to understand the mechanics of the game she's in.note 
  • Stock Light-Novel Hero: Mercilessly parodied through the premise "What if the standard light novel guy was shown up by his mother in the game just like in real life?"
  • Story-Breaker Power: All moms in the game get this, and someone is sending out hacked items to corrupt them with even more power.
  • Surprise Incest: In the OVA, when Masato gets amnesia, he is instantly attracted to Mamako. Eventually, he declares his love for her, then grabs her and tries to kiss her. A kraken attacks them and then he suddenly regains his memories.
  • Tan Lines: In the OVA, Wise and Medhi develop tan lines after sunning themselves at the beach.
  • Too Much Information: When Mamako's clothes are destroyed by a Slime, she complains she was wearing a thong. Masato yells he didn't need to hear that.
  • Trapped in Another World: According to Wise, anyone transported to the game world can't leave unless they can improve their relationship with their mother.
  • Unexpectedly Realistic Gameplay: When Wise's MP is drained, Porta provides her with a ton of MP restoring potions. The problem is that Wise's stomach becomes full just from drinking a few and she becomes sick when she tries to drink more, unlike in regular video games where players can take as many potions as they want.
  • Unstable Equilibrium: All mothers in this game are granted extremely broken gear and stats at the start, gain experience and new skills by the truckload at the drop of a hat for seemingly no reason at all, while their children have to face the burden of Early Game Hell and having all of their kills stolen from under their noses by their mothers. To put it into perspective: answering a question correctly nets Masato 10XP, while Mamako gets 30 just for being there.
  • Unwanted Harem: Subverted as Masato actually wants a harem. However, by volume 3, the girls he's adventuring with don't see him as a man anymore. Amante, the antagonist of volume 3, explains the reason for this is that the presence of a mother at the center of the party slowly turns the group into a sort of family, effectively killing any chance of members of the party developing romantic feelings for each other.
  • Weaksauce Weakness: Both Wise and her mother are specced as Mage characters who rely on their magic to do damage, so being hit with just a low-level sealing effect will cripple them instantly.
  • The Worf Effect: If there's a new boss, or another mother abusing illegal softwares to cheat, they'll always be reduced to complete pushovers by the time Mamako actually confronts them regardless of how unreasonably powerful they were just mere minutes before.
  • You All Look Familiar: Almost every important NPC Masato encounters in-game are modeled after and uses a variant of Shirase's name. Masato thinks she keeps getting New Jobs As The Plot Demands, however.
