Okaa-san Online - Episode 13 [BD OVA] - Mamako Two Hit Bikini Attack

The beach episode guaranteed that Mamako would dual-wield her swords in a bikini.

Shirase rewarded the Mamako party with a beachside resort vacation to thank them for dealing with the anti-mother faction. This, of course, meant that Mamako was going to outshine all the other girls with her pure white bikini.

The first harem joke of the show featured Wise getting embarrassed that Masato would finish blowing up Porta's float because it was an indirect kiss. Wise blasted him with wind magic, blew off his shorts, and Mamako tried to rescue her son with her own body and tiny covering. Shirase didn't help much.

Shirase insisted the group do traditional Japanese beach activities, like splitting the watermelon. After Mamako lured Masato into splitting "Mommy's melons," he threw his wooden sword at a kraken which was just low-key hanging out offshore. It gave Masato amnesia after bonking him with the sword's return strike.



Wise and Mehdi cynically looked on as the amnesiac Masato thought the beautiful Mamako was his girlfriend. Mamako, naturally, answered vaguely about the exact nature of their relationship, leading the poor boy on, and making the other girls think "here we go again." Shirase loved any kind of drama exploring mother-child relations, and this was heading into interesting taboo territory. Like always.



The eye catch made sure to have a jiggly bikini version of Mamako peeking in.

While Mamako couldn't tell that amnesiac Masato had trouble being close to a beautiful woman, the other girls let Mamako have her oblivious fun of having Masato join her for fun without the teenage male attitude. A naughty crab was amnesiac Masato best wingman to get a handful of naked mature bombshell.

Mehdi and Wise, after getting what they felt was enough sun, felt it was time to stop amnesiac Masato from crossing any taboo lines with Mamako. They did not count on being objectively inferior to the total package known as Mamako.

Amnesiac Masato confessed his love for Mamako, but the innocent and pure Mamako interpreted it as her son finally reverting to his preteen affectionate self. We'll never know how much ick the audience would feel, because that chilled out kraken decided he needed Mamako to himself.

Masato immediately got his memories and self back when he saw his mother in trouble. Then he got in trouble and had to be rescued by the OP dual-wielding MILF like always.

The dead kraken provided some great squid for evening barbecue, and things were fine until a pocket of gas knocked the tentacle into everyone else's head. The knock one-shotted Shirase into her coffin and gave everyone else amnesia! Is there going to be an episode 14 where Masato deals with all these affectionate babes? Let's hope.
