Qiubai has traveled to a world where inner and outer worlds merge. Growing up, he's surrounded by characters he's "familiar" with. There's Akizuki Airi, Akizuki Marina, Shiina Chizuru, Mashiro Chisato, Hoshizuki Kaede, Hoshizuki Suzu, Nanao Akane... and his two younger sisters, Mikan Yuuki and Kasugano Sora, who live with him. Mikan is young, but capable, mature, and energetic, taking care of the housework daily, making her a worry-free existence. Sora is slightly older, but aloof and tsundere, with a slightly frail constitution. She stays at home every day, a worrying prospect. When Qiubai turns 18, the system officially activates! Kuze Akibai: What? Just coming of age, I have to become a male succubus in the inner and outer worlds? And I even have the ability to stop time!

After his death, he travels through neon Tokyo and activates the love game system. To extend his life, he must capture girls in the game world. The faster he succeeds, the more life he gets.

"Hoshino Ruby, do you want to know the real murderer who killed your mother Hoshino Ai? Then come and make a deal with me." "Senior Mai, since no one can see you, can't I do whatever I want to you?" But after Ryoma Esaki completed the game by any means necessary, he returned to reality, only to find that a new livehouse had opened in Shimokitazawa, B Komachi's concert was being hotly discussed online, and Sakurajima Mai's new drama was being promoted on TV. The system's love game, the style has also become weird. Agatsuma Yuno, Jabami Yumeko, Ryuuguu Rena... Looking at the increasingly biased style of the strategy targets, the increasingly chaotic real world, and the girls who are coming with great momentum, Ryoma Esaki finally panicked a little. System, you are plotting against me!

Shen Bai travels through the world of anime and becomes the trainer of the heroine.

By capturing and "training" the heroine through physical connection, it can be a win-win situation.

Yuki Suho: Brother, human training and the like should have been arranged for me a long time ago.

Kato Megumi: Shiro, I also want to be noticed, please train me quickly.

Yotsuya Miko: Mystic Death Eyes, I have evolved the Mystic Death Eyes, don't move, let me do it.

Hell's Blizzard: Training, huh, I'm not obsessed with you, I just want to catch up with my sister, come behind me quickly.

Katsura Manami: This is just a massage. Saliva has a special effect on treatment, but saliva loses its activity immediately after leaving the mouth, so... Yukinoshita Haruno: If you like, I can bring my cute sister over too. Eriri: You can't ignore me anymore. I'm going to do everything I did with my mother! Looking at the increasing number of women around him, Ritsu Haga decided to run away first, otherwise even if he is a succubus, he can't stand it!

As the Queen of Succubi, I appeal to the entire demon world for help: To corrupt a 17-year-old boy, I have transformed into the Otherworld Welfare System, attached myself to him, and begun my seduction!

The hymn of humanity is the hymn of courage!" Beep! You have awakened your seductive nature, making Goto Ichiri yours... "Do you believe in gravity?" "Human encounters are meaningful. If you want peace of mind, follow me." Beep, you can now stop time. The limit is five seconds. If you want more time, I command you to... Shinomiya Kaguya... "Enough! Five seconds is enough to dominate the entire world!" "And then I'll kill you, you bastard, in less than a second!"? Gazing at the invincible figure approaching, his fist piercing the sky, and behind him, the determined faces of the heroines who have overcome their fate, completed the trials, and grown. There were even many Taiman Ninjas, Magical Girls and the beautiful superpowered girl Succubus Queen whose lower abdomen trembled with phantom pain. Can reconciliation be achieved?

In a world where men and women are superior and inferior to each other, Jinghe Qiucao and Jinghe Ashaji have been in love since their marriage. However, Ashaji seems to be busy with work recently.

However, at this critical moment, a group of kind people gathered around Jinghe Qiucao and worked together to help Ashaji protect the relationship between husband and wife. The hot girl trio: "Teacher, you don't want to reveal your identity as a succubus, do you?" The elf princess: "Mr. Qiucao, please help the elves." Jinghe Qiucao: "Ashaji..." Ashaji: "Be gentle."

The ruins of the labyrinth, silent for countless ages, welcomed a new master.
