" This...is " Tanjiro was shock.
' Can this achieve by human ? This strength...' he thought while looking at the destruction caused by a single wave.
" Sugoi Dekai !!! " the pig face, Inosuke said, while they are stutefied, Allen already walk back to Yuechan.
" Are you okay " she said gently.
" Un...it's thank to you. " he said while looking at her affectionately.
" About what you said earlier. What do you mean by that ? " he ask, even he knew the answer.
" Idiot, you know what I mean. " Yuechan said bashfully.
" Is it true ? I'm not handsome, not rich or not so powerful, are you okay with me ? " Allen said to her.
" Dummy, it is because of you, and no one else. " Yuechan tell him, erasing the inferiority and heavy feeling in his heart.
" Come here, Yue " because of his happiness, Allen hug Yuechan. They look face to face to each other, before Yuechan close her eyes and brought her beautiful lips to him.
As for Allen, he might not have experience, that doesn't mean that he doesn't have knowledge.
Then, he also brought his lips toward to her.
As their lips met, for them, the world seem stop.
Yuechan hug him with her two hands in his neck, while Allen's one hand is on her waist and the other is on her hair.
Their kiss lasted for dozens of seconds before a surprise voice enter their ears, parting their lips with a bridge of saliva.
" A--Allen-san and Yue-san, your sibling right ? It's incest. " Tanjiro said to the new love birds.
" Huh ??? Tanjiro-san ? What are you doing here ? Allen ask normally, but for Yuechan it's the opposite, she immediately hide on Allen-s jacket, not even daring to peek.
Allen laugh lightly to his girlfriend, before he patted her head.
" We're here from the beginning, we even help you. " Tanjiro didn't know wether to laugh or cry, hearing his answer.
" I didn't know that you and Yue-san are love, Okaa-san told me that your sibling. " he said to them.
" Oh about that, we didn't develop our feelings at that time, so we lied. " he said while remembering the first time they met, then he look at his girlfriend, Yuechan are also peeking at him, then they smile to each other.
" Then congratulation, Allen-san and Yue-san. " Tanjiro congratulate them, then he remember his gentle little sister cooking practice.
' You have a tough rival, Nezuko. ' he thought, he won't tell this to his little sister, because she still have a chance to be together with him, even a mistress, because the current era of Japan never forbade having a two or more wives.
" But more importantly, what are you doing here and why are you wearing the demon slayer uniform. ? " he ask sternly.
" After that incident that happen to my family, I realized that I'm completely powerless. I'm afraid that, that girl might come back. That's why I apply to Demon Corps, and Giyu-san recommended me to a former hashira...and.." Tanjiro wanted to explain more, but Allen stop him.
" I get it...I get it..., but you better go back. There's a Lower Moon in this mountain, don't worry I deal with it. " he said before walking away with Yuechan, while they were holding hands.
" But...sigh... okay.. " he wanted to help him when he hear about the Lower Moon, but looking at the damage he caused, he stop, and besides, Inosuke might have broken bone from the impact earlier, and there's also Zenitsu with a bunch of injure demon slayer.
He walk to Inosuke before giving the pig face a piggyback.
" Monchiro, who is that boy, he's so powerful and I think he is close to our age. " Inosuke even manage to ask, even his shoulder are bleeding and have broken ribs.

" Yue, what will I call to you right now ? Hubby or Honey or Dear or Sugar or Baby or Pillow...how about Peaches. " Allen said to his girl excitedly while they are hunting the Lower Moon.
" Why so cringy...Yue are just fine, Al " she said, then she called him with his nickname given by her.
" Well up to you, Yue. " he said.
They hunt or simply to say, they date for more than half an hour before they encounter 3 demon.
1 man and 2 female. They have the same feature, red-dot patter , white hair, and wearing the same style of yukata.
" Onee-san, Okaa-san, I told you that we should escape. " the young girl earlier in the river said, shivering.
The busty older woman look to Allen and Yuechan, then she look at her ' son ', nervously.
She wanted to leave, but she was also afraid of her ' son '.
" Okaa-san, Onee-san, the purpose of being a mother and elder sister is to protect their son or younger brother. " the ' son ', the Lower Moon 5 said.
Hearing this, they completely turn pale, paler than their skin.
The ' mother ' and ' daughter ' doesn't have a choice, they lifted their hand, but a voice beside them stop their action.
" A family is to protect each other. Not to use each other "
There they saw their ' son ' and ' younger brother's ' head roll on the ground, before turning into ashes.
" Gomenasai, Gomenasai. We were forced to.. " the pair of ' mother ' and ' daughter ' cry.
" Then atone your sins. " he said before holding their forehead and transfer his profound energy, and ' curing ' them.
" Let's go back, Yue " Allen walk back to his girlfriend and they left, leaving the two ' demon '.
