In the one of the guest room in Butterfly Mansion, Levi wake up from his sleep and smiled slightly when he noticed Yuki who was still sleeping in his arm. He then looked at the window and noticed it's still quite dark with just little yellow-orange light in the horizon.
He just waited like that for few minutes until Yuki begin to stiring-up from her sleep "Good morning little brother!" She said while stretching her arm in the air.
"Good morning~" Levi said then kissing her cheek.
"Hehe~" Yuki giggled while caressing her cheek that just kissed by him.
After that they went to take a morning shower in the bathroom that Kanae had shown them yesterday. As expected of the bathroom of a mansion, it has an onsen for bathing and a large self-cleaning area, for the hot spring pool itself, it is outside the room next to the room for cleaning
When they got to the bathroom, they found no one there except the two of them. Due to the Japanese habit of only bathing once a day, which is at night to close activities, they are not surprised by this either.
After cleaning their bodies quickly, they then move to the hot spring pool and soak there enjoying the cool morning air with Levi leaning on a boulder and Yuki on his lap.
"You know... It's not that bad if we can life in this world like this forever." Yuki said while looking at the scenery around them and listening the bird chirping in the morning.
"And left our mom and your new sisters~?" Levi said teasingly.
"Of course not! We can bring them here together, but how about our school life in our home world? " She snapped at him.
"Hahaha, school will be useless if you have brother who have the ability to go to another world or universe" Although in the first chapter he said he will study seriously, but it was before he got his gloden fingers which is the Vermeil and his other power. He then countiued "If you want we can drop from school and adventuring countless worlds with everyone else~"
Hearing what her brother said, Yuki shook her head and said "There's no need for that, after all our childhood will not be repeated and we will only go to school until the age of 18 and compared to the rest of our age that is quite a bit of time."
Knowing Levi has Vermeil with the [Shop] function, she believed there would be something that would make them live long, and if that wasn't available then they could go to another world to obtain magic or change their race to Angel, Demon, Dragon or some other mythical creature.
"After all the School Arc isn't that bad, we can add 'some' girls to your harem~" She added teasingly.
Levi just speechless toward the last part of her statement and said to her "You're helpless older sister" while hugging her sister naked body.
"But I'm your lover too~ and I know you love me~" She said, she turned around and faced Levi then snuggling at his chest.
"I wouldn't say no to that." He then lifted her chin and kissed her lovingly.
After he let go of her lips, she then said to him "When you gonna use your [Throne of Waifu] skill?" She asked questioningly, from that skill name alone, she knows that when Levi activates that skill, it must be a girl that worth to be a waifu.
The lovely atmosphere then turned to be a bit serious, Levi then said to her "Well... I want wait a bit after we settle our base in this world, but on second thought, we'd better increase our strength as soon as possible, but then again it would be weird if we just brought in a new person like that and had to explain it to Kocho sisters, so we might just wait for the right moment."
Yuki pondered his words for a moment then nodded in agreement. "You're right"
After all suddenly summoning someone and forcing them to work for you is disguting, call him hypocrite or what but he didn't care cause he didn't want this skill to begin with, it's just his past self want this skill for unknown reason and he cannot remember his meeting with the one who reincarnated him so he didn't know why he choose that skill.
Anyway it's tantamount to kidnapping someone from her original world and suddenly becoming his 'slave' just because he is the 'master' of the summoning process.
He had an idea or two as to why he had chosen this skill, which was because it was clear the name of this skill called [Throne of Waifu] is very close to the [Throne of Heroes] from Fate series. But different from just summoning Heroes in Fate series, this skill of his can summon all female / Waifu in multiverse be it Heroes, normal human or even monster as long as it belongs to the Waifu category.
And as a former otaku he can't help but choose this skill, because obviously as long as he is an otaku he will have the Waifu he crave.
Now he can choose to never use this skill at all, but it's also good to draw a Waifu from a world he doesn't know about so he has a reason to go there if the summoned Waifu wants to return to her home world.
(A/N : Now I have no guilt when MC use this skill.~(^з^)-♡ )
They continued like that until finnaly the dark sky turn to yellow from the rising sun, they finally came out of the hot spring and put on more casual clothes and not their kimono from yesterday because after this they would be training with Kanae.
With Levi wearing training pants and a simple withe T-shirt while Yuki just a tank-top and and a short. They knew they would attract attention by wearing modern clothes nowadays, but since this was a closed mansion and when they came here they didn't meet a lot of people, so they let it be.
Just as they opened the door out of their room, what greeted them was Kanae that smiled warmly in front of them "Hello, Good morning~"
""...Good morning.""
