Game Detail

◆Story

The hero is an invincible hero.
The Rocelia group attacks him, aiming at the Hero Energy, the source of heroism…!

The Rocellia group’s naughty temptations are coming.
And there are even some familiar faces there…!

Will the hero be able to break through the temptation and thwart the ambitions of the Lothéria group?

Game System

The attacking roselia group is a blow to the hero’s attack.
(Bosses require multiple attacks.)

Clear the stage while avoiding them at times.

The stage will be cleared when the cadre waiting at the end of the stage is defeated.

There are a total of 5 stages, and after clearing all of them, the boss of the Roselia group will await the heroes.

Various women will approach the main character. If you get caught, enter the directional key to escape!
Be careful not to fall in love with the naughty temptations..!

While caught, the yellow gauge decreases.

When this reaches 1, one heart below will be reduced. (The maximum number of hearts is three.)

When all the hearts are gone and the yellow gauge reaches 1 again, the game is lost.

Even if you lose, the game is not over. (except in some cases).

Although there is a disadvantage, it is easy to unlock the game, so feel free to lose a lot.

About the executives (area bosses)

Four executives, area bosses, await at the end of each area.

The patterns of defeat are,
Before the battle”, “Normal”, “2nd stage (a certain number of energy is reduced)”, and “Begging for your life (after the battle)”.
There are four types of defeat.

Regardless of the pattern of defeat, the dialogue will change the second time.
In addition, the player will be seduced before the battle by the content of the previous defeat, so if you take advantage of that seduction, you can see the second week immediately.
Example: Defeat by “begging for life” → Temptation by “begging for life” before the battle → Riding the temptation, you will see the second week of defeat by “begging for life”.

*However, if the battle progresses, they will not do the previous temptation.
e.g.) If you are defeated by “second stage” and then defeated by “normal”, the next temptation that occurs before the battle will be the “second stage”.

Defeat and state of affairs

Basically, you will not be GAMEOVER by temptation.
Also, once you are defeated, you can easily be defeated, as the dialogue changes, temptation enters when you are restrained, and so on.

There are a total of five types of abnormalities.
Hands, Feet, Chests, Mouth, and Buttocks.
The number of the five types is as follows.

There are three levels of depth (indicated just below the yellow bar). (The display is just below the yellow bar).
At the third level, you will not be able to refuse the temptation of the choices of the target part, or you will be tempted when you are restrained.
(except for area bosses).
