chapter 1

His name is professor Toili last, a middle-aged man, who is still a virgin. He is a genius in all fields but his life feels empty because he cannot fall in love. His hobbies are reading manga and watching anime.

Today Professor Toili experienced a strange event. He was raped by his childhood friend and killed by that woman. Maybe because he got a girlfriend, and maybe it could be called a yandere.he is now in another world using someone else's body.

(You have become a hero spirit for saving the earth from the catastrophe of the Goddess of lust that will enslave humans on earth, you get the 'gate of Noble phantasm' prize and get the passive 'super growth' skill)

'That doesn't surprise me, alright what is your name, system?' Toili used the mind not to talk because there was a waist with a small hole

(Don't have name, please give name)

'Alright, now your name is Taka, oh one question, where are we now?'

(Although I am a woman that does not fit the name taka but not bad, now we are in a universe that is an average human, more specifically is DxD high school) The system says in a tsundere voice

'I see, hmmmm, actually you want me to fight the Goddess of lust? You don't have to pretend to be a system, that woman will look for me, because I can satisfy her lust right ?, Goddess of love 'Toili thinks that there is something, why has he not been able to fall in love? Apparently there is a Goddess hiding in her soul

(truly a man who is called a super genius, exactly, but you can also make her a wife, fufufu, you are hit by the curse of love, I'm also can't cure that curse even though I am a goddess of love, it seems like I used to curse someone)

'Now is not the time to discuss about it, now is the time to take care of the enemy ahead, now I am Issei Hyoudou' thought Issei.

(It's easier because Issei Hyoudou's appetite is big so I decided to put you in Issei Hyoudou's body)

"By the way, Issei-kun, are you still alive? That date was really fun," Raynere said while making a spear of light with her magic

"Well, it was really fun, unfortunately you are too early to make me fall in love, maybe a million years come to me " Issei said in a slightly insulting tone. And bring up the sword Excalibur And open the scabbard, the scabbard is also called Avalon. it Can regenerate stamina can cure all kinds of diseases, poisons and wound.

"YOU !!! THAT SWORD !! ARE YOU NOT JUST A HUMAN WITH SCARED GEAR TWICE CRITICAL ??!!!" Raynere said angrily, his aura came out and she fired a spear of light towards Issei Hyoudou.

Although Issei is still weak and still human, but he has a lot of treasure in the 'gate of Noble phantasm'. But that is not necessary, with Excalibur and Avalon alone is enough, because Avalon is also called absolute defense. So he used Avalon to take the attack, with the left hand holding Avalon and the right hand using the Excalibur sword

'Let's learn to fight, even though I can't use magic. Because I don't have mana, so it's better if Avalon is put into the body, so that I have a magic circuit, I can already learn magic from first seeing magic, even if it's only a spear of light' Issei put in Avalon into his own body after receiving Raynere's attack, so Issei jumped towards Raynere. Swinging his sword towards Raynere,

'maybe this is my karma because I killed a lot of people who have SCARED GEAR' Raynere thought she was resigned because she already knew that ,what Issei was holding was a holy sword. with that sword Issei strength at ultimate class devil.

Strangely, Raynere even closed her eyes in resignation. Seeing Raynere close her eyes like someone who wanted to commit suicide so Issei decided to snap his fingers to Raynere's forehead

"Why don't you kill me right away with that sword?" Raynere wondered why Issei did not immediately kill her, her eyes filled with tears as if a small child crying was not given her allowance.

"Oh, I can release you but there is one condition" Issei said while disappearing the Excalibur sword. Although Raynere's sexy outfit seduces Issei, Issei has control over his own body.

'I must leave here immediately before Rias and her friend come' Issei did not intend to meet a succubus like senpai.

"Oh, don't tell me you want my body? I refuse," Raynere said, covering her chest nervously. But Raynere's mind was 'but that wasn't bad, I was only told by Azazel-sama to observe the red dragon emperor'

"Hahahah, it's really funny, you're a virgin woman afraid of the first time, Don't refuse first, I just want to learn about magic, so show your magic" Issei said while mocking her.

'strange man' Raynere thought

"Grrr, all right, using magic is simple, just imagine and recite the spell which flows to the hand, 'the longer the spell the stronger the magic and the more which you use the mana stronger the magic', let me explain the fire ball" Raynere explained at length ,and chanted the spell fire ball

"That's too easy, okay you can go but one suggestion for you, if you get in my way again then death will meet you," Issei said as he turned back and walked.

Raynere breathed a sigh of relief but Raynere took a step back because Issei stopped and looked at Raynere while saying

"Be careful with Kokabiel, have you heard of the 'chaos brigade' organization?, yes he is one of the members of that organization, so I suggest you go to Azazel to report it, if he doesn't believe it, say that the red dragon emperor guarantees it"

And Issei walking again disappeared in the darkness of the night

'Chaos brigade ?, Well, I will report to Azazel, even though I am punished, that is nothing compared to Kokabiel' thought Raynere

________________

Issei who was walking back to his house, he was being followed by a black cat.

'Hey, goddess of love, is behind me a youkai disguised as a black cat?' said Issei while stopping at a fork in the road.

( Exactly)

"Be careful, curiosity kills the cat" Issei said while looking at the black cat with a sharp look.

The cat also stared at Issei's gaze with his fur all standing up.

Issei reached the front of the house, at that time the black cat was still following him so he decided to catch the cat

"Enkidu" Issei said and the gold chain came out from behind Issei towards the black cat, but the black cat avoided the gold chain, so when the black cat jumped Issei made a restriction

"divide prefect cube" And the pink border surrounds the black cat.

"So what's your name? And why are you following me". Issei said while lifting the pink cube which contained a black cat inside. As Issei already knew the black cat's mind Issei said beforehand "You can't go anywhere, of course you can't contact your friends. Be my pet"

After Issei said then he walked to the door of the house and he opened the door of the house and he said "I'm home"

'well no one is home, well from Issei's memory, he only has a father who is working in the government transportation department, his mother died in a plane crash while going to work abroad as a diplomat, recently his father wanted to marry again, maybe because Issei is out of control '

and walked to his room and closed the door then locked the door. Why did he lock the door? Because sometimes his aunt comes to his house. And she has a habit of not knocking on the door before entering the room, his aunt lives in Chiba, but why does his aunt often go to Kuoh town? Because his aunt is often a substitute for his parents when there are school problems, and the reason his father wants to marry again is because his father doesn't want to disturb his sister-in-law, it's because his aunt still doesn't have a lover or his aunt is not married.

(As a gift of our meeting I will give you a card calling the heroic spirit, do you want to use it?) Ask the Goddess of love.

'Alright, I'm too lazy to fight, it's better to use the card to summon the heroic spirit, so the Goddess of love calls the heroic spirit'

(Yes Boss)

Swissssst

Purple runes came out of the floor. And there appeared a witch wearing magic clothes and a veil.

" you are me-"
