Underground Idol Group’s Nijigasaki Parody Sparks Debate: Theft or Tribute?

From our other sites

The story

On 5ch’s Love Live! board, controversy erupted after an underground idol group ran a promotional event parodying a live show by Nijigasaki High School Idol Club — sparking protests from hardcore Nijigasaki fans known as “Niji-shin.” Some posters argued the flyer design and song titles were copied so closely it amounted to outright plagiarism, while others countered that the poses and costumes fall well within the industry’s common visual vocabulary and saw nothing wrong with it. The thread split sharply over where parody ends and homage begins.

Don’t get so worked up over a parody like this…

These are otaku obsessed with an anime about idols, yet they look down on actual idols — so it's probably more like, 'how dare some lowly underground idol group parody the almighty Nijigasaki.'
3AnonymousSep 10, 2026 11:38
What is going on with Pikaere's sense of ethics, seriously
5AnonymousSep 10, 2026 11:39
The details match exactly, and they even used the same song titles — that's straight-up theft, so I get why people are mad.
7AnonymousSep 10, 2026 11:40
By the way, looks like Nijigasaki itself has done some copying too

If Nijigasaki's going to demand an apology from the underground idol group, they should apologize to iDOLM@STER too Re: #7
9AnonymousSep 10, 2026 11:41
Figured this was just people picking a fight, but it's actually pretty blatant.
10AnonymousSep 10, 2026 11:41
Did Nijigasaki kill Myo-san's parents or something?
11AnonymousSep 10, 2026 11:43
Niji-shin fans are way too obsessive, honestly kind of scary.
Are they prepared to get grilled the same way if the roles were reversed?
12AnonymousSep 10, 2026 11:43
If it were just the live show's title, fine, but
the flyer design is a total copy on top of that,
and even after the 'correction' it's still copied — that's a real problem.
13AnonymousSep 10, 2026 11:43
The composition's different too, and this kind of costume is pretty common in the genre, so some resemblance is unavoidable, don't you think?
If 'resembles another work' automatically means it's not allowed, then the Superstar!! merch with the angel/devil motif that was popular among Nijigasaki fans would count as copying too, right?
14AnonymousSep 10, 2026 11:43
First off, they should be grateful someone even bothered to parody them.
15AnonymousSep 10, 2026 11:45
If anything it reads as respect to me… but I guess to a Niji-shin, respect from some lowly underground idol group isn't respect at all.
16AnonymousSep 10, 2026 11:46
'The composition's different too' ← how exactly are you looking at this lol
17AnonymousSep 10, 2026 11:46
The fact that they copied the flyer and then quietly edited it proves they never got permission, so how is that supposed to count as respect for the content?

Love Live! Straight-Up Copies a Chinese Manufacturer's Costume → Chinese Fans Go Ballistic! Official Account Gets Mass-Brigaded and Flamed : Oreteki Game Sokuho @ Yaiba https://share.google/CkzAfnJVf9eZWoe0M

Pikaere's clearly doing this on purpose — there's already precedent of Superstar!! ('Spasta') making the news for this exact thing







19AnonymousSep 10, 2026 11:49
The moment Nijigasaki itself started copying costumes,
Pikaere was fully intent on steering the conversation toward Re: #18.
This guy is seriously anti-Superstar!!.
43AnonymousSep 10, 2026 12:05
Re: #41
I mean, for Superstar!! it was the official side doing Re: #18 in the first place…
20AnonymousSep 10, 2026 11:49
Don't get all bent out of shape over some 1,000-2,000 yen live show.
21AnonymousSep 10, 2026 11:50
If Nijigasaki's management doesn't act, the Niji-shin fans are going to crush these idols completely on their own.
Nijigasaki's management should really put out a statement.
22AnonymousSep 10, 2026 11:51
Nijigasaki doesn't even do live shows of its own,
so Niji-shin fans should just be grateful, honestly.
29AnonymousSep 10, 2026 11:57
Looks like they've covered Printemps songs too, so it seems like they just genuinely love Love Live! — kind of sad they're getting dogpiled this hard.

Re: #29
Getting genuinely furious over what some tiny, no-name idol group does is just small-minded.
32AnonymousSep 10, 2026 11:58
By the way, this is what they put out after deleting the Nijigasaki stuff

35AnonymousSep 10, 2026 12:02
Re: #32
That's pretty funny honestly.
51AnonymousSep 10, 2026 12:11
Wish people would have a bit more of a big heart about this.
That's how the strong are supposed to behave, isn't it.
59AnonymousSep 10, 2026 12:16
Re: #51
People with big hearts don't do illegal streaming, harassment, or defamation.
They don't post sneering comments or leak pirated videos either.
68AnonymousSep 10, 2026 12:27
Re: #2
This thread's looking down on underground idols too, huh.
So does that make everyone on the Love Live board a Niji-shin?!
70AnonymousSep 10, 2026 12:29
Re: #68
Honestly feels like a lot of people here do like Nijigasaki — I mean, most active Love Live fans these days are into Nijigasaki anyway.
72AnonymousSep 10, 2026 12:30
Re: #70
If most people supposedly love Nijigasaki, then why are CD sales only 2,000 copies?
73AnonymousSep 10, 2026 12:31
Re: #70
Yeah, that's true, but still…
78AnonymousSep 10, 2026 12:36
Also, they should apologize to Ai Kawashima over 'Kaika Sengen' ('Blooming Declaration'), which rips off her song 'Ashita e no Hikari' ('Light to Tomorrow').
80AnonymousSep 10, 2026 12:42
Re: #78
Wasn't the Natsumi episode in Superstar!! season 2 said to rip off some movie or another?
Did they ever apologize for that?
Also, the song 'Kaika Sengen' actually resembles 'Ashita e no Tobira' ('Door to Tomorrow'), not that one.
And Road of Major's 'Taisetsu na Mono' sounds a lot like 'Mahou Tsukai Hajimemashita' — was there ever an apology for that?

Background and Points of Debate

Underground idol groups running parodies that borrow flyer designs and staging from licensed franchises while performing original songs are nothing new, and these are usually done without official permission. In this case, opinions split between those who saw the close match in design and song titles as outright “theft” and those who viewed it as “tribute,” an extension of derivative-work culture. The thread also brought up past cases where another idol franchise’s costumes sparked imitation controversies on social media, framing this less as a one-off flare-up of emotion and more as an ongoing debate over where licensing rights end and parody begins. That said, as of this thread neither the underground idol group nor Nijigasaki’s management had issued any official comment.
