Morikawa is a walking Crowning Momentof Funny. From his over-the-top outbursts about how destiny screwed him over, to his treatment of his horoscope as his bible, and the memorable Episode 15 where he loses to Emi. But the one massive source of comedy from Morikawa is probably anytime he gets called...
Episode 79. Oh God, Kamui, where did you learn the term "Booby Stars"?
Episode 80. Every single line by Ren until he regained PSYQualia.
Episode 82. Ren sticking out his tongue at Koutei after losing to him.
Kenji is finally happy that he won against Ren. Cue to the MC saying "HOWEVER..." which leads to Yuri and Gai apologizing to him. The look on Kenji's face is priceless. And that happened right after that Testosterone Poisoning, Hot-Blooded scene of Great Daiyusha.
Miwa's explanation on the All Stand 3 Rear Guard rule is hilarious. Morikawa is retired in favour of the Shop Manager, WITH WINGS!!!
Episode 83. DAIGO and his not so Gratuitous EIGOU. As expected from a graduate from Harvarda -WISH!
Kai's appropriate timing of FINAL TURN left and right is also quite funny.
Izaki couldn't get any fish. It's funny not because a fish leapt up right after he said that, because if you remember Morikawa had been wrestling with a variety of fishes in the background earlier on, and he caught them barehanded.
Episode 89. Team Q4 and Team Battle Weeds. As the four players flip over their starting Vanguard, we're treated with an upbeat battle BGM, until...
Sharlenesnaps, resulting in a Battle Aura and gave Kamui a scolding so hard until Kamui changes from using "Ore" to "Boku."
Episode 93. The return of "Kyun kyun RAIDO!!"
Episode 94. Leon and Kyou just completely ignoring the antics of their minions to go off and have a cardfight on their own.
Episode 95. Kamui was waiting for his opponent, who was running late, cue to the sound of a carriage, and Nagisa steps out from the carriage and PROPOSE to him, in front of the audiences!!! Kamui's reaction was like...WTF!?
The preview of Episode 96 has Kamui wearing a white tuxedo.
Episode 96. If the end of Episode 95 fails to make you laugh, Episode 96 brought it up to eleven with Team Handsome's randomness flying around following Nagisa's "proposal" and Kamui's reaction.
Morikawa's solution #2 - Transfer into Aichi's school.
Morikawa's solution #3 - Live in Aichi's school but, this is quickly shot down as only students and their guardians are allowed into the school grounds.
Morikawa's solution #4 - Be Aichi's father. The look on Misaki's face is PRICELESS.
Naoki asking if he can re-ride Discharging Dragon, just so he can make it more Hot-Blooded.
Naoki's victory dance after he won against Kourin, and there are audiences around.
Shingo saying that he wasn't there for Kourin but for Aichi.
The whole thing with the Football team.
Episode 110 - 112.
Morikawa's envy towards Izaki having to battle Kourin during Miyaji vs Hitsue school battle. After it's over, Miwa tells Izaki to run as Morikawa chase after him because of it.
Shingo being way overconfident while fighting Miwa, just because he hasn't see him in any Vanguard magazines. Not a good idea...
Naoki's ways of asking Mai to teach him how to battle after he loses to her....in an intimidating way. Until Misaki and Aichi comes in. Hilarity ensure.
This becomes especially funny in the dub when you consider both Mai and Misaki have the same voice actress.
Shingo's match against Emi. Once again Shingo's overconfidence habit rears it head again, while at the same time he's in the dark about Aichi and Emi being siblings. He not only LOSES to her, his 'so-called' plan fails.
Naoki telling Suiko that she doesn't belong in a sailor uniform. The reactions of the rest of the Vanguard club says it all.
Then comes Suiko's response in saying she wants to make Naoki her pet in a creepy manner. Cue Oh, Crap faces from the others.
Episode 133. Tetsu's flashback of Ren trying to get him into Cardfight!! Vanguard. This includes: Swapping his lunch for a deck, putting a deck in his shoe locker, getting his goons into Vanguard, and stalk him when he's in the toilet.
Episode 139. When Misaki is told about the romantic legend of the tree by the lake, in the English dub, she compares what she heard to "being in prison".
Episode 149. The Student Council President and Vice President of Miyaji Academy tries to sneak up on Naoki, Solid Snake style. IT DOESN'T WORK.
Episode 159, English version. In the Japanese version, when Kai is bragging about how powerful his new Overlord is, Ren sounds somewhat impressed and scared. In the dub? Ren replies "Oh my, I'm all tingly." in a completely uncaring tone of voice. You can't watch it and not burst out laughing at the sheer audacity of Ren being flippant to Kai in that situation.
