Zettai Meirei Isekai Soushin Party!

He no longer gets excited by sex with his beloved wife.
Fujio Takahiko realized this about himself on the night of their second wedding anniversary.
He had always thought of himself as being rather indifferent to sex. But he vaguely realized that the real reason wasn't that.
Soon after getting married, Takahiko began having dreams. The same ones, over and over again.
--The lewd customs of the village where he was born and raised.
--A banquet held every night during the summer festival.
--A female and male writhing and panting in the darkness. The vulgar fragrance produced by animal-like sexual intercourse.
Unable to bear the sheer horror of the customs, he fled his hometown.
Takahiko realized that the religious rites held secretly there had planted an indelible sexual inclination deep in his heart. As he gazed upon his wife, Manami, sleeping with her ripe beauty and adorable face, Takahiko felt a dark heat building up in his erection. And he knew that this heat could only be quelled by returning to his hometown...
"Kagachi-sama... I offer you comfort."
The words spoken by the lips of the woman he admired came vividly back to Takahiko's mind.

Tunnel Escape is a rogue-lite exploration RPG/ADV set in a city infected by a zombie virus. It combines action and strategy in a fusion of intense gunplay with turn-based combat, item crafting and a deep skill system. Each bullet shot, each grenade thrown and each step taken will count towards failure or success.
 
EXPLORE THE UNDERGROUND LABORATORY

On the run from the spreading infection in the city, Beatrice discovers the entrance to a secret biological laboratory. Documents mention the existence of a successfully developed vaccine, sending her on a journey deep into the complex as she becomes humanity’s last hope.
 
UTILIZE AN ARSENAL OF WEAPONS AND SKILLS

Beatrice will need to defend herself from the dangers lurking below. Unlock unique guns, each with their own benefits and downsides; use throwables to blast enemies into pieces, blind them, stun them or set them all on fire. Even a strong kick to the face can turn the tide of battle in your favor - time to unleash the power of high-heels in close-quarters-combat!

In addition to raw weapon power, Beatrice can learn hundreds of different skills. Every gun has its own set of active skills, for example unlocking the potential of rapid fire for the pistol, using birdshot to hit all enemies at once with the shotgun, or emptying an entire magazine into the undead horde in one go with the automatic rifle. Supplemented by a huge number of passive skills for offense and defense, Beatrice gets access to a growing number of strategic options.

Enomoto Ryoka is a childhood friend and the ace of the girls' basketball team.

The year is 1887.
Humankind has been assailed by demonic invaders from hell. For a time, humanity's future was uncertain... until brave soldiers arose who fought back the demons. These soldiers are called heroes.

One such hero, a man named Theo, has a goal in mind: take back the city of Manc from the demons who control it, the Halfas family. But the daughters of said family ended up being a lot cuter than he expected...

One day, Tachio, an ordinary office worker, is suddenly transported to another world overrun with dark monsters known as Yamimon.

However, the moment he comes into contact with Kurenai,
he fuses with her special battle suit, Gear.
Thus, Tachio fights alongside her as her suit during battles,
while searching for a way to return to his original world (while being made to take care of everyday things at home).
