Yarimon Master: Using Cheats to Fuck ’em All! — Full Review

What if Pokemon had an R-18 mode? That’s the pitch behind Yarimon Master (ヤリステメスブター), a full-scale monster-collecting RPG by circle Bosom Studio (にゅう工房) where every trainer battle has a very explicit reward for winning. With over 120,000 copies sold, a 4.8/5 rating from 26,000+ reviews on DLsite, and a dedicated DLC expansion, this isn’t just another throwaway hentai game — it’s one of the most acclaimed doujin RPGs of the past decade. Here’s why.

Gameplay: What Makes It Unique

At its core, Yarimon Master is a GBA-era Pokemon clone built in RPG Maker — and that description seriously undersells it. There are 151 collectible monsters (Yarimon), each with unique pixel art and profiles. You explore an overworld, catch wild Yarimon, build a party, and battle trainers to become champion. The pixel art nails the Ruby/Sapphire aesthetic so well that it triggers instant nostalgia.

But what sets this apart from every other Pokemon clone is the Cheat Tackle — a guaranteed first-strike, 100% accuracy, one-hit-kill move that you can use once per battle on Normal difficulty (unlimited on Easy, for those who just want the H-scenes). This single mechanic transforms what could be mindless grinding into actual decision-making: do you nuke the enemy’s strongest monster immediately, or save your Cheat Tackle for a tougher fight ahead?

The developer went out of their way to remove every friction point that plagues both Pokemon and hentai RPGs. Wild Yarimon are always capturable (no RNG pokeball nonsense), moves can be freely swapped anytime, and an anti-inflation system prevents the late game from becoming a boring steamroll. Japanese reviewers consistently praise the game’s polish, with many noting it feels more like a commercial release than a doujin project.

What Makes It Fappable

The game’s central rule says it all: beat a female trainer, get an H-scene. This “reward on victory” loop turns every trainer encounter into foreplay — you’re not just fighting to progress, you’re fighting to unlock the next girl. And with 66 unique female characters, the variety is staggering.

The H-content runs on a “rapid-fire” philosophy. Rather than a handful of long, drawn-out scenes, you get nearly 100 animated scenes (228 CG base images with 5,000+ animation frames) that cycle through quickly as you progress. One Japanese reviewer described it as “standing soba” — you consume one girl after another in rapid succession. Each defeat brings a new character, a new body type, a new situation. If you’re the type who gets bored watching the same scene on loop, this game was built for you.

The character designs span a wide range — from cute trainers to mature women, each with distinct visual personalities. Genre tags include outdoor sex, hypnosis/brainwashing, consensual, and virgin scenarios, so there’s genuine situational variety beyond just the character designs. The animation quality is solid for a doujin RPG Maker title, and every scene comes with its own artwork rather than recycled poses. The game also includes a gallery/collection system so you can revisit any unlocked scene at will.

One thing to note: the scenes lean into the dominant “winner takes all” fantasy. The setup is inherently one-sided — you beat them, you get them. If that premise clicks for you, the sheer volume and variety here is unmatched in the genre.

Characters & Art

The art direction pulls off a clever dual identity. The overworld and battles use GBA-style pixel art that genuinely looks like a lost Game Boy Advance title, while the H-scenes and story cutscenes switch to full anime-style CG illustrations. This contrast works surprisingly well — the retro gameplay makes the high-quality CG reveals feel like genuine rewards.

The 66 female characters aren’t just palette swaps. Each has her own design, personality snippets in battle dialogue, and unique scene artwork. The monster designs (Yarimon) are equally creative — 151 original creatures that manage to feel distinct despite the massive roster. Completionists will find plenty to hunt for with the built-in Yarimon encyclopedia and scene collection tracker.

Story (Spoiler-Free)

Here’s where Yarimon Master genuinely surprised everyone. What starts as a lighthearted Pokemon parody gradually reveals a darker, more serious narrative running underneath. Without spoiling anything, the game weaves in a conspiracy plot involving mysterious experiments and a threat that extends far beyond the monster-battling world.

One reviewer compared the storytelling to Final Fantasy-level ambition, noting the ending delivers “theatrical Pokemon movie” levels of emotional impact. The tonal whiplash between the crude premise and the genuinely earnest narrative is part of the charm — you go in expecting trash and come out genuinely moved.

Pros & Cons

Pros

• Cheat Tackle mechanic makes every battle a strategic decision, not mindless grinding
• 151 Yarimon + 66 heroines — massive content volume for a doujin title
• ~100 animated H-scenes with unique artwork for each character
• Polished QoL — no RNG captures, free move swapping, smart level scaling
• Surprisingly strong story that goes beyond “excuse plot”
• 4-8 hours main story, 11+ hours for full completion — great value
• Multi-language support (JP, EN, CN, KR)

Cons

• Individual H-scenes are short — breadth over depth (the “standing soba” trade-off)
• No full voice acting — moaning SFX were added in v4.00, but no spoken dialogue
• Scene variety is narrow — most follow the “defeat and dominate” formula
• Animation is solid but not AAA quality (it’s an RPG Maker doujin title)
