Demon or not, once you're past 100,060 years old your body's bound to start acting up.

The Tour de France is the only time each year I confirm Luke's still alive!
9AnonymousAug 24, 2026 20:03
When a Seikima-II member eventually passes away, will the official account really put out something like 'He has returned to the Demon World!'?

If you image-search 'Zenon Ishikawa,' his bare face just pops right up.

Re: #18
That's just his 'disguise for hiding among mortals' (a stock tokusatsu-hero line).

Re: #18
He did a bare-faced talk session with Sōru Tōru on YouTube — the content's actually pretty interesting too.
19AnonymousAug 24, 2026 20:07
A demon who's also a Buddhist priest?
I honestly don't know what you're talking about.

Re: #19
The other titles — Kakka (Excellency), Denka (Highness), Chōkan (Director-General), Sanbō (Chief of Staff) — are based on each member's rank in the Demon World,
but this guy's 'Oshō' (Priest) is just a nickname he got for his calm vibe.

The doorknob-cover guy?

That's Luke Takamura lol
28AnonymousAug 24, 2026 20:12
Weren't they basically a KISS cover band?
29AnonymousAug 24, 2026 20:14
Since it's just his disguise for hiding among mortals, that doesn't mean he's immortal……
30AnonymousAug 24, 2026 20:14
This demon's also 100,000-and-something years old, so that's rough.
33AnonymousAug 24, 2026 20:17
Isn't it weird that Zenon Ishikawa Oshō is 64 while Demon Kogure is 100,000?
36AnonymousAug 24, 2026 20:19
Make sure to peel a pear for anyone who visits him in the hospital.
37AnonymousAug 24, 2026 20:20
Lately the lineup's such a mix of old and new members that finding a stand-in is probably no problem.
38AnonymousAug 24, 2026 20:20
They call him 'Zenon' but then go and use his full name lol
40AnonymousAug 24, 2026 20:21
His disguise for hiding among mortals is just an old man, after all.
42AnonymousAug 24, 2026 20:27
I always thought Seikima-II was just Demon Kogure doing it solo.

That's Hound Dog.

Did you guys ever own their Famicom game? (´^ω^`)

Re: #43
I had it, so what?
47AnonymousAug 24, 2026 20:35
It's because his face is painted that he can't breathe through his skin.

Re: #47
As long as it's not gold or silver paint, he's fine.
48AnonymousAug 24, 2026 20:35
For some reason I always thought he was 'Dai-Oshō' (Grand Priest).
49AnonymousAug 24, 2026 20:35
Re: #12
He's the kind of act that falls into that category, so yeah —
Funassyi would probably get the same treatment if it ever 'died' too.

Re: #1
I'm from the generation that listened to Demon Kogure's late-night radio show, and it was genuinely fun back then.
One of the good things about being a Shōwa-era kid.

Re: #53
Oh, that Director Nakayama thing?
64AnonymousAug 24, 2026 20:53
Well, I guess if you've lived 100,000 years, something's bound to wear out somewhere.

Re: #64
Pretty pathetic for a demon to have farsightedness, back pain, and frozen shoulder.
68AnonymousAug 24, 2026 20:58
Re: #61
The average lifespan for demons these days is around 100,076 years.

Re: #68
It's stretched to 100,081 now.

Background and Key Points

Seikima-II formed in 1982 as a self-described “demon rock” band, performing in full corpse-paint-style makeup and never breaking character in public: each member holds a “Demon World” rank (Denka, Kakka, Chōkan, Sanbō) and a fictional age in the tens of thousands of years, a bit sustained for over four decades on Japanese TV and radio, including Demon Kogure’s well-known late-night radio show that shaped a generation of Shōwa-era listeners. Zenon Ishikawa’s title, “Oshō” (a Buddhist priest’s honorific), fits that same in-character device, and the band’s official announcements lean into the lore too, framing member deaths as members “returning to the Demon World.”

The thread doesn’t really divide into opposing camps; it moves between two registers on the same news. One is pure gag material, riffing on the gap between an illness and a “100,000-year-old demon,” and joking about how the band would eventually announce a death. The other is quieter and sincere: posters from the original radio-listening generation recalling how much the act meant to them, alongside people surprised that the members have real, searchable faces once the makeup and stage name are set aside.

What the thread glosses over is that Zenon Ishikawa Oshō’s title isn’t just in-universe flavor text — he is in real life an ordained Buddhist priest, which is why that particular stage name was given to him rather than invented from nothing, unlike the purely fictional Demon World ranks the other members carry.
