Responsibility 1

Yuuki was moving based on his lust since he was under the influence of the aphrodisiac that was made by Aphrodite.

Rias was the same since along with the good feeling that she had for him it was impossible for her to stop the influence of this aphrodisiac.

Aphrodite is an ancient Greek goddess associated with love, beauty, pleasure, passion, and procreation. In her life as a goddess there no one who could resist her beauty and as a goddess her ability was based on both mental and alchemy. Her alchemy was a top-notch that she could use it to create an aphrodisiac that would make anyone cloud their minds in lust instantly. More importantly, it wasn't a curse or something bad that made people feel that their bodies were very hot and unless that person had goodwill on the partner of the partner it was impossible for this aphrodisiac to work.

This aphrodisiac was a support item rather than a debuff or negative effect on someone.

That's why Avalon couldn't erase the effect of this aphrodisiac since it wasn't a debuff, curse, or negative effect.

Cao Cao had prepared everything for his plan and knew that Yuuki had something that was able to purify or cure any negative effect but this aphrodisiac wasn't a negative effect rather something that similar to buff in the game. He had also left some members of Hero Faction in that artificial place since he knew that Yuuki was very popular among girls and he was hoping for them to be able to buy a time for him. He was gambling to see whether it was working or not but it seemed that he had won the gamble.

Cao Cao came back and after he had finished his mission. He saw that it was quite a mess and he could see both Rias and Yuuki in the middle. He knew that this guy was very lustful but he didn't expect that it would be this much. He wasn't sure why he felt attracted to him and it might be because he was the one who had changed him to female. He walked toward and could see that he attracted the attention of this guy.

Yuuki, who was under the influence of an aphrodisiac, felt both thirsty and hot. His mind was clouded with only one thing that was to solve this thirsty and hot feeling on his body. He grabbed girls after girls and even Rias who was also under the influence of the aphrodisiac. He had become a beast in heat and he saw someone who was walking toward him. He could see that the pants on that girl were a bit damp and he didn't hesitate to push her to the bed since the people around him were dead tired. He pushed this girl to the bed until suddenly something popped inside his head.

[Quest: Save the underworld!]

[Quest Goal: Defeat the enemy before they destroy the underworld]

[Reward: System lottery 3x]

[System tips - There are a lot of people who want to make the world turn into chaos. Stop them as soon as possible before they destroy the entire underworld.]

"......"

Yuuki stopped and felt a bit of a headache. He blinked his eyes after it had been a while for him to receive a quest to 'Save the underworld?' He was wondering what had happened only someone hugged his neck gently. He could see that it was a girl but his heart stopped when he saw the girl in front of him, "Cao Cao?!" He moved back in surprise and would have never expected that he would almost make Cao Cao's loss of virginity in his female form. His mind was blank while looking at his surroundings. He blinked his eyes since he could also see Rias there.

Cao Cao blinked her eyes, "It's a shame. You've woken up...." He stood up

Yuuki only realized that he was naked and hurriedly created clothes along with a mask to cover his body. He looked at Cao Cao and asked, "What did you do?"

"Nothing. I am only trying to support you. You like that red hair devil, right?" Cao Cao smiled.

"...."

Yuuki sighed, "I am not sure what you're planning but I'll go back now." He stood and wanted to walk toward Rias but his body was hugged.

"It's impossible for me?" Cao Cao asked while hugging him.

"..."

His mind was really complex since it would be lying to him to not have an interest but he knew that Cao Cao was male and he was the one who had changed his gender.

Cao Cao chuckled looking at his expression and said, "Well, I won't tease you. I'll leave now with everyone but can you escape from this artificial space?" He didn't say anything again and walked toward the group of girls then used one of the devices on her body to teleport them along with herself.

Yuuki saw Cao Cao suddenly surrounded by a mist along with the girls around him. He saw that they had disappeared only leaving both him and Rias in this artificial space. He could see that Cao Cao had a quite disappointed expression on his face earlier. He crouched down for a while and covered his face with both of his hands, "What the heck am I thinking?" He shook his head and looked at Rias and knew that it was a very bad situation. He took a deep breath and was ready to be responsible for her. He walked toward her and suddenly Rias was hugging him while trying to kiss him. He used his magic to wake her up.

"....."

Rias blinked her eyes and said with confusion, "Yuuki?" She suddenly realized that she was hugging him and remembered what they had done earlier. She also held her lower body since it was quite sore.

"Calm down, let me heal you first," Yuuki said and placed his hand on her stomach.

Rias tried to push him away but when she felt a warm and comfortable feeling she decided to not stop him. She suddenly let out tears when she thought about what both of them had done.

"I am sorry. Let me take responsibility for you."
