Shanison’s 3rd Anniversary Eve Turns Into a Commemorative Art Flood — 5ch: ‘Nicchi looks so cute in this’

The story

With the 3rd anniversary celebration for the smartphone rhythm game “Shanison” (Idolmaster: Shiny Colors) just a day away, fans launched a dedicated thread on 5ch’s News VIP board. Posters kept dropping commemorative artwork and preview images of the next gacha banner one after another, along with update news for the enza (browser) version. Partway through, though, the thread got hit by a troll who kept spamming nothing but meaningless 10-digit numbers, prompting regulars to discuss ways to mass-filter the posts with an NG (blocklist) word. The thread’s original poster calmly shrugged it off with “If it gets taken down, I’ll just rebuild it,” and in the end the commemorative art generated more buzz than the troll ever did.

The "Hiragana Gang" (idols whose stage names are written in hiragana) are cute too

There's an enza (browser) version update today too

Ngghh, couldn't we just mass-block these with the NG word regex ^[0-9]{10}$?
90AnonymousOct 30, 2026 10:43
Ngghh, what's even the point of trolling a thread that's nothing but dirty jokes and sexual harassment anyway?

It's a motion-sensor type that activates when you reply to it
Kind of like a "Notorious B.I.G."? (a pun on "Notorious Monster," MMO slang for a rare trigger-spawned boss)

If this thread gets taken down, I'll just rebuild it, so go ahead and drop it, no worries

I love that Toru seems like the type who'd casually announce he needs to take a dump

Background and Key Points

“Shanison” is a smartphone rhythm game based on Idolmaster: Shiny Colors (Shinymas), and at the time this thread went up, its 3rd anniversary event was just a day away. In the pre-celebration mood of the thread, fans mainly shared commemorative character artwork, previews of the next gacha banner, and update news for the enza (browser) version, which drove most of the excitement. Partway through, however, a troll showed up repeatedly posting nothing but unrelated 10-digit numbers, and the regulars discussed countermeasures, including setting up an NG (blocklist) word via regular expression. The way the thread’s original poster calmly handled it — saying “If it gets taken down, I’ll just rebuild it” — reflected the laid-back mood typical of a fan thread. Neither the timing of the troll’s appearance nor the meaning behind the numbers was ever clarified in the thread, so whether it was simple disruption or had some specific intent remains unknown.
