the sworn group surfaced on Shibuya Channel’s music desk in October 2009 under the headline “the sworn group 10/8 @ O-nest”, published 21 October 2009. The piece treated the band as a MySpace-era newcomer stepping off the platform into Tokyo live houses — with SHIBUYA O-NEST as the geographic anchor for an ongoing self-produced event run.
Member names, venues, and festival timelines reflect 2009 reporting, not current activity.
Lineup as listed in 2009
The article named six members with roles attached:
| Member | Role |
|---|---|
| Yuuki Tetsuya | vocals, guitar |
| Oono Takashi | guitar, chorus |
| Tsukamoto Ryo | keys, chorus |
| Suzuki Manabu | bass, chorus |
| Shiraishi Shogo | guitar, chorus, keys |
| Yamagami Tomoko | drums |
Yamagami Tomoko joined as drummer in September 2009, immediately before the band launched its Oiwake Yurayura residency concept at O-Nest.
From MySpace top news to festival shortlists
the sworn group formed in September 2008 and was framed as a notable NEW COMER that had “escaped MySpace.” Despite the short history, the band landed in MySpace top news, where commentators praised refined songwriting and standout vocals.
Milestones from the chronology:
- October 2008: finalist at a Yamaha-hosted music event
- November 2008: MINAMI WHEEL debut
- July 2009: nominated for final selection as a newcomer audition candidate for ROCK IN JAPAN FES “RO69JACK” and SUMMER SONIC
- RO69 JACK outcome: confirmed participation on a 2010 compilation CD planned for release through an indie label operated by Rocking On
That last item positioned the band inside Rocking On’s pipeline — not merely on a one-off festival bill but on a label-backed compilation scheduled for 2010.
Oiwake Yurayura — live plus artwork at O-Nest
In September 2009, with Yamagami on drums, the sworn group started Oiwake Yurayura (追分ゆらゆら) at SHIBUYA-O-NEST — a self-produced event merging live performance with artwork exhibitions. The series ran monthly through December (four consecutive months).
Co-bill partners included notable names. The report singled out FOE, led by Sodai Masaichi (曾田茂一), described as someone who praises the sworn group, among other high-profile collaborators. The residency format implied O-Nest as a home stage while the band converted club nights into mini festivals with visual art on the walls.
Sound — “Bitter Sweet Symphony” and a 2010 supernova tag
Critical language in the source compared the band’s sound to “Bitter Sweet Symphony” — delicate songs where bitterness and gentleness coexist, paired with passages that could turn dynamic and aggressive. That combination, the writer argued, made the sworn group feel overwhelmingly original on stage.
The closing forecast was explicit: a band expected to leap as a “2010 supernova.”
Sodai Masaichi quote
The feature included a direct endorsement attributed to Sodai Masaichi:
“I feel it’s brilliant how they land Japanese lyrics with such a high level of musicianship ♂ I’m looking forward to the thunder dance!”
(Stylized Japanese slang in the quote; the praise is for Japanese lyric writing and musical skill.)
Upcoming live dates
The feature appended a future live schedule block:
26 October (Mon) — Aoyama Tsukimiru Kimi Omofu
Support/co-acts listed: Hana no You ni, acari, Sasaki Ryo (pogs), hello!
1 November (Sun) — MINAMI WHEEL ’09
Osaka Shinsaibashi Americamura AtlantiQs — performance from 19:00
10 November (Tue) — the sworn group presents “Oiwake Yurayura” Vol.2
@ SHIBUYA O-NEST
With TLKY. (Terakoya) plus special guest FOE and others
1 December (Tue) — the sworn group presents “Oiwake Yurayura” Vol.3
@ SHIBUYA O-NEST
With RAINYDAY (from Asahikawa), Fukurouzu, and others
These dates document late-2009 routing between Osaka festival circuit, Aoyama rooms, and the O-Nest residency — the same Shibuya live-house cluster that sits uphill from the scramble.
Shibuya through Oono Takashi’s eyes
The piece closed with a “image of Shibuya” answer from Oono Takashi:
“A city that asserts itself.
If you let your guard down, it mercilessly leaves country people behind.
When I had just come to Tokyo, I was honestly scared (lol).”
That quote ties the band profile to Shibuya’s reputation as an intimidating, self-confident district for newcomers — useful context for why O-Nest residency mattered as a foothold.
Shibuya live houses and the street layer
O-Nest belongs to the Shibuya O-Group circuit documented throughout sibch.tv’s music coverage. Shows there draw the same youth streams that cross Shibuya Station daily — visible in real time on the Shibuya Crossing live camera. For archive readers, this entry captures the sworn group at the moment MySpace hype, Rocking On compilation placement, and four-month O-Nest art-live hybrids converged — weeks after the 8 October O-Nest date referenced in the headline.
