Virtual Idol (Miku) sits at the apex of the support hierarchy in Universal Tower Defense. Based on the global vocaloid phenomenon Hatsune Miku, she's not just a cosmetic addition—she's a mathematical necessity for clearing high-wave Infinite Modes and challenging Raids. Her ability to amplify surrounding units by a statistically significant margin transforms standard formations into "God Squads."

Unlike DPS units, Miku doesn't deal damage directly. Instead, she provides percentage-based Damage and Range buffs that scale linearly with the power of units she buffs. This ensures she remains "future-proof" regardless of how high damage numbers climb in future updates.

The Mathematics of 28%

The Miku guide centers on understanding why percentage buffs outscale adding another DPS unit:

The efficiency gap widens as individual unit power increases. With Godly traits on your DPS units, Miku's 28% buff becomes even more valuable than a sixth damage dealer.

The Sniper Trait Imperative

Why Sniper over damage or speed traits? Miku doesn't attack enemies—she buffs allies. Her critical stats are irrelevant. The entire value proposition rests on the Range Multiplier (x1.3).

This near-doubling of the "Buff Zone" enables looser formations, lane bridging on multi-lane maps, and safe positioning away from the track front.

Deployment Strategy

• Wave 1-10: Don't place Miku. Focus on Farm units and cheap DPS
• Wave 15-20: Place base Miku once primary DPS line is established. 18% buff is immediately cost-effective
• Wave 30+: Upgrade Miku to expand range as you widen DPS footprint
• Evolution: Prioritize Super Star evolution over evolving secondary DPS. Global 28% buff usually provides more total team DPS

The "Deathball" Formation

Place Miku first in the center of the intended kill zone. Place your main carries (SJW, Ragna) in the immediate ring around Miku. Place Berserker units on the outer edge of Miku's range (facilitated by Sniper trait) to catch enemies entering the zone.

For summoner units like SJW: If Miku buffs the summoner, the summon stats snapshot the buffed values. A 28% buff to SJW is effectively a 28% buff to his entire Shadow Army—exponential scaling.
