Last week belonged to 星街すいせい (Hoshimachi Suisei)‘s new single. This week the chart corrects: ビビデバ (Bibi Deba) reclaims #1 with 492K views while 星をみる少女 (Hoshi wo Miru Shōjo) drops to #10 as expected after its explosive debut week. But the real story this week is what’s happening in the new entries — four simultaneous arrivals, each with engagement numbers that demand attention, and at least two of them are going to be on this chart for a while.

Top 5: ビビデバ Returns to #1, OBF Surges, and Marine’s BooooM!!! Arrives

ビビデバ is back at #1 with 492K weekly views and 176.4M total. ジョー・力一 (Joe Rikiichi)‘s OBF climbs three spots to #2 with a strong 395K and a notably improved 1.93% engagement rate — the highest it’s shown since entering the chart, suggesting the fanbase is still actively engaged rather than just passively streaming.

The biggest single-week event on the chart is 宝鐘マリン (Houshou Marine)‘s BooooM!!! entering at #4 with 362K views, 506K total, and a 4.51% engagement rate. That’s the highest engagement in the top 10 this week by a wide margin, and a +6,228 position jump that tells you this is a brand new release hitting hard and fast. Marine has had a consistent multi-entry catalogue presence on this chart for months — dropping a new original into the top 5 on debut week is a statement.

Four New Entries — and the Engagement Numbers Are Wild

This is an unusually active week for new arrivals. Four songs enter the chart simultaneously, and together they paint an interesting picture of where energy is flowing right now.

IRyS‘s MUSE enters at #12 with 160K views — its entire total, being a launch-week release — and a 14.45% engagement rate that is the highest on the entire chart. For context, that’s almost double the next-highest engagement entry this week. The mifumei and KANAURU production from the DANGERyS album is activating its fanbase at an extraordinary rate out of the gate.

緋八マナ (Hibachi Mana) of Nijisanji enters at #17 with パッチワーク・ヒーロー (Patchwork Hero) — 108K views, 509K total, 1.17% engagement, and a +6,212 jump. A strong debut for a Nijisanji solo original.

龍ヶ崎リン (Rene Ryugasaki) of ななしいんく (Nanashi Inc.) enters at #26 with Don’t Make It Harder — 93K views on 114K total, another launch-week entry. Nanashi Inc. is an independent VTuber agency that doesn’t appear on this chart often; an entry this high on debut week is notable.

白嶺六花 (Shiramine Rikka) enters at #36 with 事切れて、またね。(Kotogire te, Mata ne.) — 78K views, 223K total, and a striking 6.17% engagement rate. Another strong debut engagement figure suggesting a tight, activated fanbase.

Other Climbers Worth Noting

VOLTACTION‘s De Lu Lu continues its impressive run, jumping 27 more spots to #19 with 102K views and a 1.62% engagement rate — its highest engagement showing yet. This song has been climbing steadily for weeks and is now firmly mid-chart with genuine momentum behind it.

パン野実々美 (Panno Mimimi)‘s Take You Higher enters at #20 with a +346 jump and 407K total views — but 0.20% engagement tells you this is catalogue discovery rather than a fresh release generating new fan activity. A meaningful re-entry nonetheless.

At #54, 式部めぐり (Shikibu Meguri)‘s collaboration with mifumei — 秒速 (Byousoku) — enters with a +108 climb and 85K total, 0.05% engagement. The timing alongside the IRyS MUSE release (also mifumei) is probably not a coincidence; producer spotlights can lift multiple releases simultaneously when a name starts trending.

Two more entries deep in the chart deserve a mention: hololive English -Justice-‘s SUPERNOVA SUPER GIRL at #66 (45K, 255K total, 2.06% engagement, +6,164) and 羽子田チカ (Haneta Chika)‘s オイメアルシー (Oimeearushii) at #81 (37K, 43K total, 9.27% engagement). That engagement number on Haneta Chika is extraordinary for a back-half chart entry — tiny total view count, very activated audience.

Suisei’s Catalogue Settles, Marine Holds Multiple Entries

After two weeks of dominating the chart with both a new release and a massive catalogue presence, Hoshimachi Suisei‘s entries are settling back toward their natural positions. 星をみる少女 drops from #1 to #10 as the debut spike fades, and the back-catalogue entries (#23, #24, #25, #35, #40 and so on) are all down several spots each. The chart is normalising after her new-release disruption.

Houshou Marine, meanwhile, now has BooooM!!! at #4 alongside six other entries spread through the chart — making her the dominant multi-entry artist this week now that Suisei’s catalogue has cooled slightly. III with Kobo Kanaeru holds at #13, スキスキDieスキ超Ayeシテル at #16, and several more between #21 and #69. Marine’s catalogue consistency is a weekly constant at this point.
