## Analyst notes (AI-assisted)

A 2026 visual novel adventure by Hulotte, published by Kagami Games, about a lazy angel living with the protagonist in a comedic supernatural slice-of-life setting.

This title sits in a niche sweet spot: 100% positive reviews, a compact lifetime net of $8.6k USD, and steady monthly residual income of $2.2k-$2.7k/mo despite zero promotional activity in the past 12 months. The 64% key-share ratio and two-language localization (Simplified Chinese primary) suggest a micro-targeted Asia audience that has stabilized post-launch. Angle depends on buyer intent: a publisher seeking low-risk, high-sentiment catalog depth should evaluate acquisition; a revival-focused buyer might unlock Western localization or console ports to unlock the $3.6k/mo opportunity estimate.

- Most realistic play: acquisition
- Risk (market): Micro-audience title with only 1,024 lifetime units and no traction outside Simplified Chinese; expansion beyond this cohort is unproven.
- Risk (tech): Built 3.6 months ago; long-term engine stability and platform support dependencies unknown.
- Risk (other): Developer Hulotte has only two titles in catalog; studio continuity and post-acquisition support risk unquantified.

Suggested first moves:
1. Request full review corpus in Simplified Chinese and any regional usage telemetry from Kagami Games to understand whether audience is East Asia-locked or genuinely untapped in Western markets.
2. Validate the $3.6k/mo opportunity estimate by stress-testing elasticity (-1.0) and discount-promotion impact: zero promos in 12 months may indicate publisher restraint or audience saturation.
3. Conduct IP and trademark clearance on title and character names; confirm Hulotte retains all rights and Kagami Games has no backend revenue share that would complicate acquisition or revival investment.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
