Chapter 40 features Kenichi's sister coming to visit her brother at the dojo. Shigure and Apachai attempt to make tea for her. It doesn't end well. Then she shows them how to make tea and they're utterly shocked at how skilled she is.
After Ryozanpaku disbanded for a short while, Kenichi and Mui take care of the dojo by themselves. After a few weeks of this, Kenichi and Mui finally kiss only for the masters to come back HOLDING BACK A RAGING ELDER.
While the Ryozonpaku gang is infiltrating Yami's base in Okinawa, Kensei Ma and Akisame are forced to fight two armed members of Yami. Akisame was going to take the left one and Kensei the right...and then they realize that the left one's a girl. What ensues is by far the most epic, paper, scissors match ever, made all the more funny by Kensei's insane determination and will.
ERO WILL PREVAIL!!!
After a close encounter with Hermit, Niijima decides to investigate Ryouzanpaku. Hilarity Ensues as he meets each one of the masters (Or, as he calls them, Youkai), but the kicker is what happens when Kenichi appears; he calmly asks the masters to leave as Niijima is clearly scared of them. Niijima flips out when the Youkai apparently obey Kenichi!
It took several hours for Niijima to regain his composure.
The whole sequence of Kenichi and Ma Kensei making their way through trap-filled wilderness to sneak a peak at the Ryozanpaku hot springs, only to be treated to... this.
Apachai. Just Apachai. The guy is a walking CMOF.
Answering the phone: Apachai: "Hello. We have kidnapped your child."
Miu: "Don't answer the phone like that!"
At another time, he answers the phone with, "It's me, it's me, you know, me!" that infamous Japanese phone scam. (The con is that the scammer tries to trick people into thinking they're a loved one in desperate need in cash)
When Ethan Stanley appears to attack Kenichi at the urinal.
When Shigure and an injured Apachai started fighting Akira Hongo, one of the One Shadow Nine Fists, Akira backs off, claiming that he doesn't feel like fighting a woman or an injured man. Kenichi panics, thinking that his masters will take it as an insult, but Shigure seems delighted that someone treated as a woman and Apachai just acts grateful for the concern. It's a subtle moment, but it's a delightfully funny one.
Made even better by the Elder's commentary on the situation.
Elder: As much as you hate your past, you'll still unconsciously bring back all those painful memories! Looks like the training he is enduring everyday must be scaring him to death. I'M SO SORRY KENICHI!!
Shigure placating a feared swordsman by giving him a hoe. It only barely makes sense in context.
Said swordsman is more than a little bit of a Cloud Cuckoo Lander, he really likes attacking things, and he can attack the ground FOREVER.
When they meet that swordsman again, he's shown to be very good with that hoe, and he's an impressively competent gardener.
After visiting Miu's family grave, Kenichi decides to take her to the Botanical Gardens. He then impresses her with his extensive knowledge on plants, and he says he's reading a book about grasses that you can eat. He's reading it so when the Elder decides to leave him on a mountain to starve, he won't have to worry.
Chapter 183 has Kenichi try and jump from a cliff onto a snowmobile being driven by Miu, only to miss by about several dozen meters. Then Miu turns the snowmobile around and drives it towards Kenichi...and ends up running him over.
Kanou Shou, who's normally very confident and carefree, is trying to abscond with Miu. Kenichi gives chase by using the decorative ivy and vines clinging to the building, while shouting that the flowers are cheering him on. The look on Shou's face is a magnificent blend of WTF? and Oh Crap.
Upon meeting Natsu Tanimoto, Kenichi spends as much time worrying that he'll steal Miu as he does just being utterly floored by his good looks.
Kenichi: Oh my god, I can see roses.
Kenichi deciding to join the gardening club.
Kenichi: And from that day on, Kenichi dedicated his life to gardening innocent plants and flowers who never cornered him in alleys or tried to kick his face down his throat! He lived happily ever after!
After fighting Fortuna, the Shinpaku members are confronted by an APC. Sakaki steps up to take it out... Only for Shigure to pop out of the hatch and ask to take it home.
After Apachai hits Kenichi so hard that his heart stops beating, some quick reactions from Akisame save his life. The next day, Kenichi appears to have no memory of nearly dying. Miu confronts Akisame about it:
Miu: "I think there might be something seriously wrong with Kenichi! He doesn't remember nearly dying!"
Akisame: "Well, I guess we dodged that lawsuit."
The Shinpaku Alliance infiltrates Thor's hideout, but are discovered in seconds. How? Matsui wouldn't leave the stupid flag behind.
In chapter 117, Niijima tries to blackmail Kisara into joining the Shinpaku alliance with pictures of her being all adorable with cats. He notes that only he and Siegfried know where the digital copies are...and then Sig pulls out a disc. Niijima dives for it, but Sig destroys it (mentioning he deleted all the backups too). Then he tells Niijima that he doesn't want the Alliance to stoop to Ragnarok's level...in song. And finally he turns to Kisara and pulls out his masterstroke.
The whole 'Ryouzanpaku for kids' episode is one laugh after another. Of note are Sakaki's reaction to the dojo being overrun by children, Kenichi's reaction to Akisame's...influence on his students, and much more. It gets a bit sad with Miu near the end, but Kenichi makes it all better for her.
When Niijima first brings Kenichi news of Siegfried and his "zombie-like" ability to get back up unharmed after being knocked down, the masters start ribbing Kenichi about what a great opponent this is:
Sakaki: "Sounds like it's an interesting opponent he's got lined up for you! I've never fought a zombie before!"
Elder: "I have."
*dead silence for a few seconds as everyone stares at him. Then everyone goes back to ribbing Kenichi as though nothing happened*
When the principal of Miu and Kenichi's school, along with Ono-sensei, come to the Ryozanpaku for a visit. Miu has Sakaki and Shigure pose as her parents. When the principal decides he wants to ask 'Mom' a question, Shigure responds, "What is it, baldy?!" And while Kenichi and Ma Kensei are cringing from this blatant social blunder, Ono is trying to hold in her laughter.
From chapter 489: After an Awesome Moment from Ukita and some silly from Shiba and Koetsuji, everyone goes swimming. (Save Ukita, who's still recovering from being beaten by Shiratori last issue.) Shiratori is in a bathrobe, and confesses that he likes Ukita. Takeda is... somewhat uncomfortable. And then Shiratori gets up to get in, taking off his bathrobe, only to find out that Shiratori is actually a SHE!! Takeda's reactions are nothing short of priceless. And then Shiratori asks Takeda for advice on how to win Ukita's affection... What's greater is when Takeda pieces together that Freya, in addition to Shiratori and Kisara like Ukita, his facial expresions say it all.
Chapter 497: Kensei returns from training Rimi, announcing that he's awakened Rimi's Dou Ki, saying that she's "not the same person any more." As he says this, we see Rimi standing stock still behind him with an emotionless, glazed over expression. Ryuuto worriedly calls out to her, then... realizes that she's just asleep.
Chapter 498: The Shinpaku Alliance head to the amusement park(with a pool). Ukita see's Shiratori in a bathing suit but shows no reaction. Only when Shiratori has covered herself up does Ukita recognize "him". Ukita believes he saw Shiratori's doppelganger and tells "him" to be careful. Shiratori promptly delivers a kick to his face, with Takeda laughing at his stupidity.
During Yomi's all-out attack in chapter 503, the untargeted members of the Shinpaku Alliance start panicking. Niijima yells everyone to calm down and orders them to regroup while spanking one of the girls from The Valkyries. He puts such an effective commanding fašade that it works, snapping everyone out of it and no one, not even the girl in question, calls him out for it.
Ogata while training Rimi:
Ogata: "Anyway Atlanta.
Ogata: "Why are you wearing a gym uniform?"
Rimi: "I was told to bring clothes which I could move in easily so. I thought it was please Kensei-Sama."
Cue Kensei kicking one of the logs she's pulling down the cliff.
During Chapter 510, Freya is still stuck in Odin's wheelchair. Page 9 is hilarious with the constant focus on her butt from being crouched over and the awkward position it puts her in.
During the different catfights at the fight in the amusement park, the amount of Clothing Damage is ridiculous, adding humor to the seriousness of the fights. At one point Renka is totally bare-assed and Rachel would be baring her breasts if she wasn't covering them.
A memorable moment In and Out of Universe at the beginning of the series. Takeda, Ukita, and Koga are interrogating students trying to find Kenichi. When they here a sound from a locker, Ukita assumes he's trying to hide right under their noses. Ukita slams the locker into the middle of the room... and a doll pops out claiming "Kenichi will beat Ragnarok!" While Koga and Ukita are pissed at the taunt, Takeda is laughing his ass off at how stupid they look.
Ukita: "Hey, Takeda, you want to tell me what the hell is so funny!?"
Chapter 529, Shigure tells Miu and Kenichi to go back to Ryozanpaku and by the time she's finished Miu is already saying goodbye. Kenichi decides to stay, then Shigure points to his would be training partners (aka Kagerou and Apachai) and he immediately gives his farewells.
Shigure: ...this is for the part I hate about you. *slices her opponent's hair*
Chapter 544. Shigure is being held prisoner by Yami. They're afraid to put anything in the room with her, because she can use anything as a weapon, so she's buck-naked and has her hands and feet encased in solid blocks of resin. A guy who looks rather like Colonel Sanders is intent upon convincing her to give up her father's secrets of steel. The entire time he's trying to talk to her, she says only one thing:
