This is a collection of futas made by mugenfutacharsmaker edited by Ea-Nasir using an old version of Futinahri. The code has been highly tweaked to add many features and optimizations.

MagicaViperTharja and SS2-KurokoD4 are stages

Ea-nāṣir:

I should note two very important things though:

1) The chars are only compatible with each other. They are not compatible at all with any chars outside of those I have edited.

2) All chars work for ikemen nightly only, doesn’t work on the build from mugenfuta.com

AI scene control: Players can reposition scenes, change sex positions, adjust speed, and decide cum timing.

AI teleportation for smoother scene transitions.

Player victims can control scenes too.

New minigame: Bar goes up/down (up = aggressor wins, down = victim wins).

AI rage factor: If a victim escapes too often, the minigame gets harder.

Impregnation system reworked: Now chance-based, depending on factors like AI difficulty and cum amount.

Stamina system (Power bar): Sex scenes drain aggressor/victim stamina; affects scene effectiveness but not impregnation triggers.

Grab delay balance: Prevents continuous cumming into downed victims.

Standby system: Characters in sex scenes are ignored by others until finished.

Infinite modes: Added Infinite Cum and Infinite Impregnation options.

PvP support: Minigame optimized for multiplayer. Keep in mind that multiplayer only exists through VPN tunnel.

Zoom added (stage dependent).

Custom BGM volume control.

All characters now have movelists showing new keybindings.

Special impregnation trigger if you land many hits before cumming.

Grab sound cue added.

NoKo system: Last round doesn’t end until a player commands it, even if the opponent has no HP.

AI improvements: Better grab targeting, AI can win/lose minigames, downed/dead targets deprioritized.

Power regen for downed chars based on missing health, helps them drain cum bar faster.

Special grabs: Give aggressors power and a bit of health while draining victim stamina.

All animations synced 1:1 between aggressors and victims.

Code cleanup: Removed outdated systems (e.g., demon futa states).

Sound system standardized across all characters (group 4218).

Futinea & Victinea unified across characters for consistency.

Update 16/9/25.

-The amount of times you hit the enemy as well as the amount of times that the enemy has hit you now influence the directional minigame. The more you hit the enemy the easier the minigame will be and vice versa. This hit count is updated throughout the match and cannot be reset in any way and it also influences the impregnation chance..

.

-If you manage to score a few hits on the enemy without getting hit much yourself, you will be able to activate the auto-grab feature. This essentially causes your char to automatically grab an enemy if they are close enough without the need for you to press the grab keybinding. The keybinding that allows you to enable auto-grab can be viewed in the in-game, in-battle command list option. Note that you can always enable auto-grab: if you do not have a sufficient hit score to actually use the auto-grab then the feature will be placed on standby until you have the required hit score. A loud sound will be played whenever your auto-grab is truly enabled, whilst two quitter ones are the indicators for when you switch auto-grab off or auto-grab has been placed on stand-by..

Mugenfutacharsmaker: These characters, despite having new features, are not officially supported and are incompatible with any other character outside of this collection. It’s recommended to use a standalone Ikemen build to try them out.
