TenkafuMA!

What the game is

TenkafuMA! is a free-to-play casual JRPG for Android, developed by SG-Arts and published by Pinkcore on its Nutaku page. The player is Caesar, a self-declared badass Archdemon who decides that conquering the world is worth doing because it lets him claim every woman he meets. Battles are turn-based, the cast is collected into a harem, and the page tags the game as uncensored, with animated scenes. It is an adult comedy-fantasy game with a crude voice, and a reader who finds that tone off-putting will know within the first lines of the page.

Nothing is charged to download TenkafuMA!, its Nutaku page adds a note that in-game purchases may exist, and the news posts there print the summon rates of each event banner.

How it plays

The premise is a conquest romp, and the page is open about not taking itself seriously. It promises hilarious plots, with no need to save the world and no weird conspiracies to uncover, only Caesar breaking all the rules. The summary has him bored with ordinary demon conquest until he learns that conquering a land lets him take what he wants from the people in it, a list that runs through women, devils, angels, elves, dwarfs, princesses and generals. The developer's own site describes the same setup: Caesar is the strongest archdemon in all the land, waging war across the demon world, the human world and even the heavens, while building an army of concubines who are meant to be loving and also fierce and powerful.

The play is a casual turn-based JRPG. The key features describe battles as strategic and turn-based, with 5 different attributes and jobs and hundreds of skill combinations, under the line that the player should make the harem strong. So the loop is to recruit characters, pick their jobs and attributes, build a team and win the fights that move the conquest forward. Characters come through summoning: the news posts on the page are about limited-time summon banners that feature pickup characters, and the posts publish the summon probabilities for those pickups.

There is a layer of scenes tied to affection. The page says characters fall for the player as he collects all the HCG, and that the scenes are animated Spine CG that are fully voiced. The page describes a nudity system, in which characters can be undressed, and an option to see their real skins. It also mentions punishment-themed interactions that use props.

The pages do not give the length of the campaign or describe an energy system. Of the languages, the page lists Korean, Japanese, English and Chinese for the game.

Content and themes

This is a hardcore adult game, and the tags say so. Nutaku lists Angel, Animated Sex, BDSM, Big Breasts, Bondage, Demon, Free to Play, Hardcore, Harem, Hentai, Maid, Monster Girl, Nudity, Porn Theme and Uncensored. The genre line reads Casual JRPG. The feature list names imprisonment, fetish and cuckold themes along with discipline and bondage, so the BDSM and bondage tags are central to the pitch and not incidental.

The cast, according to the page, includes demons, angels, elves, dwarfs, princesses, generals and maids, and the monster girl tag points to non-human characters. The harem tag and the conquest premise mean the game is about collecting and dominating a large female cast in a comic, over-the-top register. The developer's site adds a second point of view on the same theme: the game aims for a mix of warmth and fighting strength in its concubine army. Art is anime style with animated Spine scenes. The page says the content is uncensored.

The official game site at tenkafuma.com opens with an age gate that asks visitors to confirm they are at least 18 and warns that the site contains sexual and violent content, so adult content is clearly signposted before anything else is shown.

Platforms and where to get it

The Nutaku page lists Android as the only platform and offers an APK download for it, with a download size of 300 mb. The game's own site, tenkafuma.com, is titled as an official site for an 18+ mobile game on iOS and Android, so it names iOS where the Nutaku listing does not. Neither page says where an iOS version is offered, so the Android APK on the Nutaku page at nutaku.net/games/tenkafuma/ is the download the pages actually give. The developer SG-Arts also has a company site at sg-arts.com, which lists TenkafuMA! among its products with a Download Now link and a Home link to the game's own site.

The pages do not give system requirements beyond the download size.

Price and model

TenkafuMA! carries the Free to Play tag, and its economy turns on summoning. Caesar's army grows through banners, and every banner post prints the odds of its pickup characters. The page does not name the in-game currency or print what any purchase costs.

As of October 2026 the news posts on the Nutaku page show how the rates are presented. A limited-time Trick or Sweet event is listed for 2026/10/7 to 2026/11/4, with a Master of Halloween summon banner whose featured SSR characters are listed at 0.6% each. Another event, Dog & Spice, listed its featured characters at 0.6% each and a combined SSR rate of 1.2%. These are per-banner rates for limited events, and the page does not state a base rate for permanent summons.

Development state and version

In October 2026 the Nutaku page lists version 2.3.0-nutaku, a download size of 300 mb and a release date of October 20, 2021. The game is clearly in live operation: the news section shows limited-time events in sequence, Blade Fury from 2026/9/9 to 2026/10/07, Trick or Sweet from 2026/10/7 to 2026/11/4 and the earlier Dog & Spice event starting 2026/08/05, each posted on the dates given. The developer's company site says SG-Arts was established in 2020. No end of service, roadmap or planned content is stated anywhere.

Who it suits and who it does not

TenkafuMA! suits an adult who wants a casual turn-based harem game for an Android phone, with comic, over-the-top writing, animated voiced scenes and a strong fetish and BDSM emphasis. It suits someone who is comfortable with gacha banners and event calendars, and who likes building a team through jobs and attributes.

It does not suit a reader who wants a serious story: the page says outright that it has no world-saving plot. Its tone and subject matter, which center on domination and conquest of women as a joke, will not appeal to everyone. A player without an Android device will find no browser version on the pages, and iOS is mentioned only on the game's own site. The banner rates are published, but the pages give no prices, so spending is something to judge inside the game.
