Fans Clash Over Mystery ‘Hai-se-no!’ Call at Rosy Chronicle Shows

From our other sites

The story

At live shows for the Hello! Project group Rosy Chronicle, a male fan has reportedly been spotted shouting a unique call of his own — “Hai-se-no!” — in place of the usual standard calls. According to a report on 5ch’s Hello! Project board, other fans nearby directly confronted him, telling him to “never say that again,” and a thread was started about it. The discussion went beyond whether his behavior was right or wrong, growing into a bigger debate about just how far fan-cheering traditions like MIX chants and calls should continue at shows today.

That 'Hai-se-no' yokai that started showing up at Shiodome yesterday (?) was back again today.
For some reason he skipped it during "Naji Ai" (a song nickname) and busted it out during some other song instead…

The only song where 'se-no' gets a pass is Lalapipi.

Let "Hai-se-no!" slide for the Ocha no Kitty-chan song too.
8AnonymousOct 5, 2026 10:19
People who shout 'hai-se-no' are just nuisance otaku, plain and simple.
9AnonymousOct 5, 2026 10:19
If you told the guys doing the 'oi-oi' call "You're loud! It's grating!" would they actually stop?
If not, you've got no right to lecture anyone else.

Re: #9
The sheer numbers are different though.
26AnonymousOct 5, 2026 10:45
Good thing he's not some geezer who gets defensive and snaps back with stuff like Re: #9.
12AnonymousOct 5, 2026 10:27
When there's a window to do MIX I get the urge to join in, but I hold back.
14AnonymousOct 5, 2026 10:28
They should just set official calls and ban everything else.
It's not like the old days when creative cheering culture used to spring up on its own.
16AnonymousOct 5, 2026 10:29
Plenty of newcomers dislike calls altogether anyway.
Stuff like 'oi-oi,' 'fu-fu,' or just shouting names is plenty.
17AnonymousOct 5, 2026 10:29
Maybe it's time to drop the fantasy that you're somehow special and just admit you're otaku for an underground idol group that shows up at underground idol festivals too. Of course MIX and 'hai-se-no' are going to happen at this point.
23AnonymousOct 5, 2026 10:39
The real problem with this 'hai-se-no' thing is
it's seriously just one guy saying it.
24AnonymousOct 5, 2026 10:40
I'm curious which song he actually said 'hai-se-no' during.
25AnonymousOct 5, 2026 10:43
Rena-chan's cute, super cute ×5!
Go Rena-chan, nail that quiet breakdown chorus!!
27AnonymousOct 5, 2026 10:46
Groups should never have their own complicated, group-specific calls.
And it's even worse when the idols themselves start lecturing fans with "here's how you say it here."
'Hai-se-no' and MIX are the best kind of culture precisely because even first-timers can join in and everyone feels united.
'8bit' is basically a song written for 'hai-se-no' and MIX.
I don't know what song they played at Shiodome, but I feel bad for Grandpa Hai-se-no.
28AnonymousOct 5, 2026 10:48
Hardly anyone in Hello! Project even does that anymore, and you're calling it unity…?
31AnonymousOct 5, 2026 10:50
'Hai-se-no'? 'Hai-se-no'?
57AnonymousOct 5, 2026 11:06
Re: #31
You can hear "Hai-se-no!" at the start of Angerme's "Tsugi Tsugi Zokuzoku."
32AnonymousOct 5, 2026 10:51
Old man! I'll back you up starting next time!

From home? lol
41AnonymousOct 5, 2026 10:55
'Ieeettaigaaa'
So that one's fine then?
46AnonymousOct 5, 2026 10:57
Re: #41
That's basically MIX though.
Stuff like the 'ja-ja' call is just a self-indulgent wank-off call.
47AnonymousOct 5, 2026 10:57
It'd be fine if guys just shouted 'Woo!' in a normal voice, but there are way too many old guys doing it in a creepy, gross voice.
52AnonymousOct 5, 2026 10:59
Re: #47
That's why I keep saying Rosy should switch to 'Yaaa!'
54AnonymousOct 5, 2026 11:03
I want Rosy's shows to be clean — no 'hai-se-no,' no 'ore no,' no 'chou zekkou kawaii' nonsense.
It's exactly because this is such an important stage in their career that I want to keep it clean and treat it with care.
Isn't that how everyone feels?
Or does everyone actually welcome it turning into an underground-idol-style scene?
56AnonymousOct 5, 2026 11:06
Re: #54
They don't even give us the kind of fan interaction underground idols do, so no, I don't welcome it.
Otaku making noise instead of actually watching the idols isn't a 'culture' — I hate it.
59AnonymousOct 5, 2026 11:07
Are Rosy fans actually vicious?
I always figured they were just a bunch of DDs (fans who like lots of idols rather than being loyal to one).

Re: #59
The most militant fanbase in all of Hello! Project.

Background and Key Points of the Debate

MIX chants and calls are a fan-cheering tradition that took root at idol shows well beyond Hello! Project, developing over time as rhythmic accompaniment to songs. In recent years, however, there’s been a growing push to keep shows welcoming to first-time attendees, and that has made many fans less tolerant of calls and MIX chants with a strong, group-specific flavor. What made this case stand out is that ‘hai-se-no’ isn’t an official call or a widely established chant — it was reportedly being repeated by just one specific person. In the thread, opinions clashed head-on between those who feel calling culture itself should be protected and those who see it as a nuisance that alienates first-time fans, with no resolution in sight. It’s also worth noting that details like exactly which songs the call was used during were never confirmed within the thread — this whole debate stems from a single on-site sighting.
