Rex opened his eyes with a groan to see Kiana glaring at him with a pout. The Kaslana had her arms crossed on her cheat and pouted at him.

"WHO IS SAKURA!?" She asked calmly through gritted teeth...

"Sakura..." Rex said as he looked at her with a groan.

"Hmph!" Kiana pouted as she looked away. "I was worried for you all night and you were busy talking about another girl."

"Wait... you don't remember Kallen and Sakura?" Rex asked. Hearing the name of her ancestor, Kiana looked at him with wide eyes.

"Y-you pervert!" She shouted with a blush, thinking that her friend got a perverted dream about her ancestor, she was not jealous though.

"Huh? What are you talking about?" He asked as he looked at her.

"Hmph."

"If I let you hide in here will you forgive me?" Rex offered as she looked at him

Hearing this, Kiana perked up a bit. Having a place to hide from Aunt Theresa and Aunt Himeko as well as a place to hang out.

"Fine." She said without any hesitation Laid her back on his bed. "Look what I found." He said with a grin as she raised a familiar flash drive.

A flash drive that has his 'research'

"Put that down," Rex said calmly as Kiana smiled smugly at him

"Nope, not until I found out what this has," Kiana said as she plugged it in his laptop and blushed. The flash drive was filled with titles that she was familiar with.

Her face burnt red as steam came out of her head. Seeing that his secret was out Rex squeaked and tried to get away from the bed only to realize that Kiana had tied his legs up.

"Y... you..." Kiana said as she faced him, bloody murder in her eyes. Instead of being scared, Rex found her adorable.

"Well, it was a nice life." wait. Is that a nosebleed?

"Pervert!!!" She shouted as she threw a pillow at him. Now any natural human hit by a pillow from a Kaslana would have found themselves with broken bones. But Rex is not one. He was a crozzo. The only thing he felt was nothing.

"You were the one who barged in my room," he said blankly as he looked at her with a sigh.

Pouting, Kiana looked at the files and was surprised that she liked his research.

"Hmph, I won't tell about this to Himeko-Sensei if you." She said as she was about to walk towards him, only to trip on one of his socks and land on top of him with a large thud.

"h-hey, Kiana are you alright?" He asked with worry in his voice. opening her eyes, Kiana was confused.

Looking close, Rex was a bit bigger than him, he was just like her father but more... Kiana leaned in subconsciously as she went to kiss him.

"Subject Rex is everything alright?" Floating towards his room was Bronya Zaychick, his little sister in all but blood ever since he met her. Seeing the sight in front of her, her hair drills suddenly stood straight in horror. 

"W-wait... Bronya." Rex said as he tried to calm the Russian down. 

"Project Bunny," Bronya said calmly as her Stand manifested beside her, cannon raised. 

"Hey! Wait! Bronya!" Kiana shouted as she and Rex tried to get out of the bed only to end in Kiana landing on top of him, her breasts smothering and putting him in a blissful state

"Nyet. Kiana Idiotka has now violated and attempted to seduce, Subject Rex. For the safety of everyone from Pervert Kiana Idiotka, you must be detained." Bronya said with a cold tone. 

A huge explosion echoed in the dorm rooms, as it sent three students flying out of the room. With Kiana and Bronya fighting mid-air and Rex... Rex plummeted on the ground in front of Mei Raiden, carrying groceries. 

"AAh, Rex-kun! Please hold on!" Mei shouted as she held the young man. Rex, seeing Mei cried happily in his mind. 

'Mei... such an angel.' He was unaware that he said that out loud making the poor girl blush as she held a passed-out Rex, and unsure if she should just take care of Rex or stop Bronya and Kiana.

In Europe, a familiar scene is happening. 

Reve Crozzo died on a bed with one arm missing. He lost it during an encounter with Raven of World serpent. It was worth it though, especially he copped some feels during the fight and she was very hot. It did cost him his arm, but was it worth it? 

Well, he did make out with her.... so, it was fucking worth it!

Now, the only problem was that not only was he no longer able to work until he had his new arm back but also...

"Durandal-sama, Please let me be the one to take care of, Reve-sama." This, he had unintentionally caused something between Durandal, his childhood friend, and Rita, his former partner. 

Now, for any man this would be heaven but... Rita has been itching to have some blackmail on him ever since that mission they had two years ago when they were both 18. 

For Durandal, he knew she was just gonna force him to endure several hours of PT (physical training) and try to probably end him after what happened to both of them 4 years ago the time she became a Valkyrie and he was a junior technical operator as well as special operations soldier doing wetwork for Otto with Rita. 

Sadly, he was wrong, far too wrong. 

Off to another building overlooking his room, Raven can be seen using a sniper rifle to look at him with an annoyed frown on her face. Not only was that pervert foolish enough to take her first kiss but now he was flirting with other women. Unacceptable.

---

Rex groaned as he opened his eyes and came face to face with a scene in front of him. It belonged to three people. 

Reinhardt Crozzo smiled as he wrapped his jacket around Kallen and Sakura asleep under a cherry blossom tree. 

"Take care of them for me." Reinhardt said as he looked to Rex, the two looked alike so much that they were like mirror images with Reinhardt being older and having scars on his face. 

"You... You're" Reinhardt chuckled as he approached him, his visage being hidden by the shadow as lines similar to those found with Honkai infection appeared on his skin, his dark eyes glowing and changing to a pool of purple with lotus and the light changed to reveal his true self. 

Reinhardt revealed himself, wearing the face only seen in the portraits in the ancestral Crozzo home. 

The greatest warrior of Schicksal, one of the greatest warrior and greatest generals of the honkai crusades in the middle east at the age of 14, Reinhardt 'Alexandros' Crozzo. The man who allied himself with Dracula. 

"and don't let the curse of Shicksal devour you, my descendant," Reinhardt said. 

"the curse of Shicksal?" Hearing this, Reinhardt solemnly nodded. 

"Yes, a curse that each generation of we Crozzo bear. To fall in love, only to have those feeling sealed away for our duty to Schicksal. For me, I had to lock away my feelings for Kallen and Sakura. For one of us, it was around the founding of Anti-entropy when his beloved fought with Schicksal, he was torn and chose to kill his heart for his mission." Reinhardt said. 

rex gulped as he looked at his ancestor. 

"enjoy the rest of your days my descendant," Reinhardt said as he slowly disappeared. "For that body will soon be mine, as arranged by my dearest friend," Reinhardt said with a sad smile. 

Opening his eyes, Rex saw that there were now three Kiana's in the room. Oh my god! Only one of them was hard enough to handle but now, three?! Wait, one of them is Auntie Teri, while one of them is Kiana. 

"A Crozzo?" The other Kiana said, wait she has two braids. Kallen? Why did she sound angry at him? 

"Wha's your problem with Rex?" Kiana said. 

"If you know what's good for you, my descendant, stay away from him." She said, glaring at Rex with venom on her voice yet, there was a certain sadness in her eyes. "Otherwise, you will experience the same pain I felt." Kallen said with a glare aimed at him. 

"What the hell's your problem!?!" Kiana shouted angrily as she stood in front of him to take her glare head on. "I don't know what's your problem with Reinhardt but Rx is different from him!' Kiana shouted as she defended him. 

Sensing a fight was about the start, Rex stood up. "I'm moving out," Rex said to Theresa only to yelp when Kiana grabbed him by his arm and dragged him away from her hateful ancestor.

If you are confused then this is the real chapter. The events of past meets present to the hectic life of Rex Crozzo is just a dream. 

The next chapters will be focused on Kallen's and Reinhardt's relationship from when they first met untill their deaths (of their physical body for kallen)

And also, one of Rex's and Reve's family member is in love with one of the founders of anti-entropy. but The Crozzo family has very tragic love lives so... you know. 

Fun Fact: 

Rex does not have a harem. But he is a part of a harem of two persons (well, technically three if you coun HoT)

Reve is terrified and paranoid around Rita and Durandal but is flirty around other women as long as they nor te immortal blades are not present. He somehow got Raven to make out with him. 

Ren and Fu Hua won't be on as they are happy. 

Otto... Otto is otto.

And Yes, Rex will die one day. 

Basically otto made Rex like theresa. Instead of being unable to age past 12 until the herrscher of death arrives, Rex has a lifespan, where if he passed it, he will slowly forget everything  and watched as all of his memories get wiped away while Reinhardt is reincarnated in his body. Wtf Otto! That's the clone of your dearest friend. 

Also fun fact, Rex and Kiana often sleep together with her sneaking in because Kiana's dormant Kaslana genes callowing her to control ice is countered and overpowered by Rex's dormant Cruz genes that will allow him to control Heat/Thermodynamics. So for Kiana, Rex is a human heater while for Rex, Kiana is a human airconditioner. 

Sneak peak: 

Rex: wait.... *looks at Bronya, Kiana, and Mei.* she's a herrcher, She's a Herrcher, you're a herrcher! Are there any other herrchers I don't know about? 

Fu Hua: *hidden Yatta noises while she enjoys her date with Ren

Sakura: *pseudo-herrscher noises*

Seele: *nervous unsure noises*

Also Veliona: Sup! 

Rex: I'm out of here!

Also Rex: Gets dragged and fought over by HoT and HoV to know which hersscher he will become a slave of. 

sneak Sneak peak

Rex: Look at this. *drags HoF Kiana inside the Hyperion*

theresa: What's wrong with Kiana?

Rex: *slaps Kiana's thigh making her blush hard* this blue-eyes white Tuna can fit so many herrscher cores.

Kiana: Rex-kun... 

Suddenly, the temperature heats up and Rex turns to see a blushing and angry Kiana.
