Marisa and Alice's Self-Contradiction☆ (魔理沙とアリスの自己(じこ)矛盾(むじゅん)☆), also known as Jiko Mujun☆ (自己矛盾☆) or Self-Contradiction☆,¹⁾ is the jidaigeki-style Cookie☆ voice drama that had been published for the infamous video's 10th anniversary on February 14, 2020.²⁾

The video starts off with a glimpse at a new voice drama's debut to the community³⁾ in 2018, but we are first sent back to 2015 where a struggling artist considers making fan content despite her beliefs. A clown⁴⁾ would approach her with a Cookie☆ request and she obliges, trapping the artist into a high through newfound popularity. 'Yukari' then helps show the basics, yet warns of the subculture's deceptive nature.⁵⁾

Our protagonist complains about bandwagon fans to 'Remilia', then Shiriri would suddenly intrude with new MAD videos and voice dramas, invoking some jealously. The scene is then interrupted by 'Remilia' and a band of fundamentalists who 'freezes' everyone⁶⁾ and preaches a return to past times, except their extremist actions becomes a bit of a wake-up call to the artist.⁷⁾

At this point, 'Yukari' delivers a crucial reality check, invalidating her exceptionalism by pointing out that she lost her 'self' and has nothing but fan content to stand on. As the protagonist panics, the clown returns to reveal that he was a director, offering her a part in his shoddy voice drama, then 'Remilia' intrudes with a fake script to sabotage the project on behalf of the fundamentalists or risk getting herself frozen.

We are finally brought to 2018, the voice drama's debut, where the artist would ultimately reject both options. Instead, the artist goes on a lengthy rant about how she hates artists who simply make fan content for quick validation, instead of producing original content, and pleads that everyone should forget about Cookie☆ to be themselves. She is frozen in a blaze of glory, then 'Yukari' gives the title drop.

• In the video, the community is split between a 'cultivation' (養殖, yōshoku) side that prioritizes growth, and a 'fundamentalist' or 'purist' (原理主義, genri shugi) side that pushes back. I noted this down since I knew that any translation attempts, before one came out, would probably get this wrong.
  • Much of the plot revolves around the concept of 'falling into Cookie☆' (クッキー☆堕ち, kukkii ochi), or 'ku☆ochi' (ク☆堕ち), when people suddenly make Cookie☆ content out of nowhere. The term's application tends to vary as some argue that coming from Rei no Are should not count, while purists that hate when the community gets 'too friendly' with one another might include them as well.
• The Fairies of Light avatars were meant to be mob characters, so their main dialogue was meant to be generic comments that you would find in the comment section of Niconico Seiga.
  • Of course, the term 'shunga' (春画) referred to erotic drawings that were allowed on Niconico Seiga, before payment processor issues axed it. It was 'R15' (rated 15) for Japanese standards.
• During a montage, the artist's Udzuki illustration was criticized by 'Sakurakiji' (サクラキジ), who was a controversial critic that caused problems if they thought an illustration in the 'Cookie☆' tag was more Touhou Project than Cookie☆, even using alternative accounts to deliver the point.
• The main plot point is 'Shiriri' (しりり), represented by 'Konjac Jelly Momoko' (こんにゃくゼリー桃子), being suspended from Twitter around June 19, 2018. In reality, he was mass reported by Koushinists suspecting that Shiriri was an alias of Kenma-P from the Jimusho Scandal, but the usual folklore attempts to explain that there was an alleged string of creators being doxed.
• In the end, a Japanese-language cover of Sammy Davis Jr.'s “Don't Blame the Children” (子供達を責めないで) by Masatō Ibu is pulled out. While the original 1967 song points out that adults are partially responsible for their children's 'delinquent' behavior by setting bad examples in the first place, Yasushi Akimoto's translation completely turns it into a comedic rant.
