Prior to the present when Diane hadn't join the seven deadly sins and currently with the Giant clan. They were in war with the human showcasing their might towards mighty strength. Caelum who saw that Diane was absent and wonder where she was but he saw a certain woman. It was blonde woman with ripped body and hard as a rock.
The woman was Metrona who utilize her earth magic able to push the thousand armies. However, it was obvious she was being overwhelmed by their barrage of attack.
"Go we can defeat her! This woman is their leader and if we defeat her then it would smooth sailing from her!"
""HAAA!!""
They thought metrona was Diane who was the true leader due the fact she was the strongest giant. Having Yoeui had broken the balance but Caelum didn't care much about balance unless his training.
'She reminds me a lot of Mereoleona.'
Caelum was only watching due to the fact the anime didn't do justice in the anime and was eating popcorn while his at it. He saw Metrona slammed her feet into the ground then created tall spike killing a large portion of their army but it results in her being exhausted.
The army saw her fall regain their morale even after their comrades had been killed and charge to finish the job of killing her but everyone came to a halt when they saw a young man picking his teeth of stuck popcorn.
"Dammit even after becoming this strong nothing could beat this."
The army couldn't believe how laid back the strange young man who summons a string removing the food stuck on his teeth ignoring the people. It was blizzard scene that no one will believe them cause even themselves do not.
"What in Britannia name are you!?"
"Me? The one shake you mama's bed."
Caelum jokingly said as he shrunk the fainted body of Metrona afterwards summon a servant of his namely Igris to heal her wounds leaving Carlin with the army. He slowly turn smiling but everyone was shaken from it as an enormous shadow looked down in them.
"Come forth, my shadow."
He had never had the opportunity to used his shadow army but for the sake of it use them. Though only the low level one but they still powerful enough to defeat them with ease.
"Slaughter only the sinners and erased the memory of those are innocent."
The shadow army glimmer finally gaining an order from their king who saw his army massacre the people involved in war. After a few minutes, Caelum return to his home leaving the blood to soak land for the people to see. Only the innocent and good nature remain. It was then words spread a crimson-haired demon roaming the land.
Caelum arrived to his personal library where he found a woman wearing a leotard hovering in the air with black most around her. He smiled approach her who suddenly smiled him instantly appeared in a tight hug.
"Where did you go!? You reek of woman's scent!? Tell me! Tell!"
He saw her Yandere smile into a slit mouth being agitate by the smell of a woman of Liliena and Alya was present then they would do the same. Caelum calm her down by give a deep kiss which made her feel weak.
"Now now no need to be jealous. I just save someone earlier no need to worry."
"I heard from Alya-sama that when you said that you always gain another woman."
"Did I just heard onii-chan having another new woman!?"
From behind him was Liliena who wrapped her arms around his neck while nibbling on his ear.
"Liliena? I thought your with mom and taking care of our daughter?"
"Well she like to spoil her granddaughter and prepare them for the 'future'"
"How many times have I told you I won't touch our daughter!"
"Haha keep saying that then the inevitable would happens and tell me would let any other man touch your daughter?"
"Of course…Not!"
"See I think you'll end up making all pure maiden."
"Is there any reason why you're here, Caelum-sama?" (Melascula)
"Nothing much but since you're here lets have some fun shall we?"
"Oh what do you bare in mind?"(Liliena)
He smirk then grabbed the two woman that cause the whole library to have the sound of moan scream throughout. Afterwards, Caelum went to visit unconscious giant who was gradually waking up.
"Where am I? Is this the afterlife??"
"Yo morning sleeping beauty how are you holding up?"
She heard someone called out to her and upon notice Caelum realize that her body had shrunk evident by being in soft and fluffy bed. Metrona could feel the magical energy in the surrounding was thicker than normal specially the earth elements.
"Let me explain what happened but I recommend resting for now."
Metrona intently listens that even if she was a giant doesn't mean she isn't smart enough to understand the vitality of information. The giantess was shocked to be in another world far different than her own. She inform that going back to her home would take sometime due some problem (System/Author) but her thought was interrupted by the sound of her stomach.
"Oh your hungry I see well let me fetch you some food."
"Thank you for everything, Uhm?"
"Oh just call me caelum."
"Metrona."
He nodded calling for a meal to be prepared and few minutes a maid came in delivering her food. Metrona felt out of place considering almost dying by the human race but dismisses it due to the aroma of the dishes laid before her and without hesitation ate the meal.
"Hey don't you want some? You've staring at me for some time now!?"
"Well I can't help seeing how cute you looking that much food and don't worry I'm not hungry."
She shrugged unaffected by his compliment due to lacking common sense in romance or flirt. Caelum unconsciousness wanted to flirt with her due not yet realizing the vitality of an essence at this time. His mind wanted her to be since specially the demon side due her overbearing and primitive mindset.
For the next few days, Metrona been frequently visited by caelum until her recovery allowing them to gain each others trust. Afterwards, Caelum happily gave her a tour of his place showcasing the beautiful architecture.
"This feel unusual being this small. Can I chanhe back to my normal size?"
"Of course but if you want I can teach you how to control it."
"Interesting…Tell me I've been meaning to ask if the woman that visited me after you left are your woman? They been really adamant of getting to know and I heard your quite strong?"
"Can you tell how they look?"
Caelum sighed in defeat after learning Liliena and Alya had been trying to corrupt her ever since she came. Metrona ask for them to spar and agreed before trying to find Alya. Surprisingly, Alya was in the training ground waiting for them.
"Onii-chan! Metrona-chan are you two here to spar or to fu-Gaaah!"
"How many times I told you stop corrupting people to be part of my harem! At first I wanted it small but now I'm trying to limit myself."
Caelum karate chopped Alya who was about speak inappropriate before gaining a number of scolding from him. She pouted but her man spoiled her by giving her passionate kiss much to metrona who felt hot seeing them.
"Hai…I don't what to do with you….Well anyway were since Metrona wanted to test my strength."
"Oh Great I'll prepare some popcorn and lubrication."
"Don't you mean butter?"
"Nah lubrication for later if you what I mean."
Alya went to the sat to watch them fight eating some popcorn while at it as her lover and metrona prepared to their spar. Caelum whom had train his physique the utmost limit he currently can took a stance. Metrona began by summon earth from below trying to pierce through caelum but he snap few of them then kick sending the projectile straight to Metrona who was unable to evade made her body solid turning iron.
It was over in an instant when she was left open and Caelum appeared from behind then tap some of her acupuncture cause her to feel limp. Her external body was sturdy but internally weak and easily broken by the precise tap.
"What happened? I felt you were still far away? How!?"
"You overestimated yourself even if you had sturdy defense doesn't mean it is flawless."
"Hahaha I can't believe I was bested by a man this easily."
Metrona grown to respect Caelum that gradually turn into romance but it took longer due her common sense far to differ than the norms and only been corru-I mean guided by Caelum's lover that she told him her feeling which he accepted in defeat.
'Please no more woman…'
