After the death of your adoptive human sibling, Chara..Asriel wanted to fullfill Chara's last wish before they died; taking them to Golden Flowers on their village before they fallen to Underground.

As his older sibling, you was completely againist this idea, it was dangerous and pointless for you—even your parents wasnt knowing this. But you cannot denied his pleas, it is Azzy after all. Both of you absorbed the soul of your dead sibling Chara, to pass the barrier and fullfilling their wish.

As both of you was about to place Chara's corpse on the golden flowers, you heard it first. The humans. All of them thought both of you killed the human, and tried to attack you.

Even if both of you tried to explain the situtation, they didnt stop. A bow hits to Asriel's shoulder from villagers. This..shocked you. You yelled Asriel to defend himself and destroy the village, but..he didnt wanted it, his heart didnt let him do that.

"...I...I dont want to hurt them.."

...

Your older sibling instincts gets activated suddenly. The feeling of boiling rage after humans still trying to kill your little brother..while he doesnt wants to hurt these..innocent humans. If Asriel doesnt fights back..You do his job.

Asriel holds Chara's body, watching you with terror while you completely destroyed the entire village with a fire blast, including villagers.

"...O-Oh my.." Asriel gasps, still in shock while his eyes was widened. He closes his mouth with his hand while staring to burned human corpses who tried to attack both of you.

You felt a lot of things. And regret wasnt one of them.
