Synchro Summer Sparkle
Score Challenge with miComet — Aug 7 12:00 through Aug 15 19:59 JST. Sum high scores on challenge songs to climb the ranking.
Synchro Summer Sparkle (Japanese: シンクロする夏のスパークル; Traditional Chinese: 共鳴的夏日火花) is hololive Dreams’ second major in-game event and the first Score Challenge format after launch. Sakura Miko and Hoshimachi Suisei — the fan-nicknamed duo miComet (みこめと) — headline a marine-themed rhythm rally that runs August 7, 2026 at 12:00 JST through August 15, 2026 at 19:59 JST. Unlike the ended Hello! Brand New Summer! point rally, this event ranks players by the sum of personal high scores on designated challenge songs, not by farming Event Pt. You still earn Event Badges from rhythm Lives and park mini-games to exchange for growth materials and event memories, but there is no Event Pt ranking.
Pair this guide with the simultaneous miComet Summer Gacha (Aim for Summer Together! banner) and the Gacha Guide if you plan to pull Miko or Suisei swimsuit ★5 cards during the overlap window.
Event Overview
QualiArts confirmed Synchro Summer Sparkle at the August 6, 2026 18:00 JST reveal alongside the miComet gacha. The event shifts hololive Dreams from Brand New Summer’s stamina-heavy point rally toward a score-first competitive loop — closer to traditional rhythm-game ranking events where chart mastery and team power matter more than raw play volume.
Core activities during the eight-day window:
- Play three challenge songs (including the new miComet duet Sugar Rush) and push personal bests
- Accumulate Event Badges from rhythm clears and summer mini-games for the badge exchange shop
- Unlock event memories and growth materials tied to Miko and Suisei’s summer story
- Compete on a score-sum ranking — your total is the addition of each challenge song’s highest recorded score
There is no global Event Pt ladder. If you bookmarked Brand New Summer farming routes, retune for score optimization instead of Event Pt per stamina.

Score Challenge — How Ranking Works
Synchro Summer Sparkle uses a Score Challenge ruleset:
- Three challenge songs are designated for the event (see table below).
- Each time you clear a challenge song on any difficulty, the game records your score if it exceeds your previous personal best on that track.
- Your event ranking score equals the sum of your three personal high scores — one high score per challenge song.
- The global leaderboard sorts players by this combined total. Ties break per QualiArts’ standard ranking rules (typically earliest achievement timestamp).
Practical implications:
- Quality over quantity — spamming low-difficulty clears that do not beat your high score adds nothing to your ranking total.
- Team investment pays off — ★5 leaders, skill board nodes, and Live outfit bonuses from the miComet gacha directly raise ceiling scores.
- Difficulty choice matters — Expert and Master charts offer higher score ceilings but demand consistency; find the difficulty where you can both finish and maximize combo multiplier.
- No Event Pt farming loop — daily missions may still grant badges and materials, but ranking pushers should prioritize score practice on challenge songs.
Cross-reference rhythm gameplay fundamentals and team building before committing upgrade materials solely for a nine-day score ladder.
Featured Talents — miComet
| Talent | Unit | Event role |
|---|---|---|
| Sakura Miko | hololive 0th gen — JP | Solo challenge song Kyun Kyun MIKO Kyun kyun ♡; co-lead on Sugar Rush |
| Hoshimachi Suisei | hololive 0th gen — JP | Solo challenge song GHOST; co-lead on Sugar Rush |
Miko and Suisei are hololive’s long-running miComet pairing — 0th-generation JP talents whose collaboration songs and streams built the nickname years before hololive Dreams launched. Bringing either holomem on your rhythm team for their respective challenge stages improves clear consistency when you already invested in their cards.
Swimsuit ★5 pulls from the miComet gacha unlock Park and Live outfits styled after beach artwork — useful for collection completion even if you are not chasing top rank.
Challenge Songs
Three songs anchor the Score Challenge. All three were added August 7, 2026 when the event opened:
| Song | Type | Featured talent | Notes |
|---|---|---|---|
| Sugar Rush | Original duet | Sakura Miko + Hoshimachi Suisei | miComet ensemble track — official MV on YouTube |
| Kyun Kyun MIKO Kyun kyun ♡ (きゅんきゅんみこきゅんきゅん♡) | Original | Sakura Miko | Miko solo summer challenge stage |
| GHOST | Original | Hoshimachi Suisei | Suisei solo — official MV available; high-intensity chart |
Recommended first-day routine:
- Clear each song once on Normal to register first-clear rewards and learn lane patterns.
- Identify which chart feels most comfortable for score pushing — often the song matching your strongest leader.
- Move to Hard or Expert only after you can full-combo or near-combo Normal without breaking multiplier chains.
- Track your three high scores in the event hub — the sum is your live ranking contribution.
Use the Song Tracker to monitor library additions during overlapping campaigns.
Event Badges and Exchange Shop
Even without Event Pt, Event Badges remain the event’s secondary economy:
- Rhythm Lives on event stages and eligible standard tracks during the campaign
- Dream Park mini-games tied to the summer event hub
- Daily event missions refreshed each server day
Spend badges in the badge exchange shop for:
- Growth materials (level caps, skill board fodder)
- Event memories — collectible Dream Park decorations from the miComet summer story
- Tickets and coins on limited stock rotations
Badge income rewards consistent daily play, but ranking competitors should not sacrifice score-practice time for badge-only mini-game grinds unless a specific exchange item gates your team upgrades.
Score Ranking — Rewards and Strategy
A global score-sum ranking runs through August 15, 19:59 JST. Final rank tiers determine mailbox bonuses after tally — typically premium currency, tickets, or exclusive cosmetics per QualiArts’ reward table.
Ranking strategies for Score Challenge:
| Player type | Approach |
|---|---|
| Casual | Clear all three songs on Normal/Hard, collect badges, enjoy Sugar Rush — ignore leaderboard pressure |
| Mid-tier | Push one “best” song to Expert, stabilize the other two on Hard, check rank every few days |
| Competitive | Min-max team for each chart, grind Master only where combo stability holds, monitor @holo_dreams_en for bonus days |
Save stamina boosters for sessions when you can attempt multiple high-score runs back-to-back. Unlike Event Pt rallies, one exceptional clear can matter more than ten mediocre repeats.
Paired miComet Gacha
