⚠️Spoilers⚠️ (Chapter 142)
Shinobu Kochou x S/O
Shinobu’s rage had always stuck with her since the day her sister took her last breath. The anger never intensified nor calmed. It was just there. So for her to suddenly have her emotions boil over was a new sensation for Shinobu. She didn’t care that her calm facade that she spent years working on crumbled. She didn’t care that her underlings would be joining her soon. She didn’t care that she held onto her sword too tight. She just wanted revenge. Shinobu wanted the demon in front of her to suffer.
The demon a few paces ahead of her, whom had introduced himself as Douma, smiled too sincerely for spmeone who just murdered someone’s lover. He wiped his bloody lips before he spoke, “My, my! Who would’ve thought I would be so lucky today! Two cuties to eat, in a row no less!”
“You bastard! Give them back!” Shinobu tightened her clutch on her sword and brought it forward, “Give me back my S/O! My sister!!”
“Oh my, so vulgar.” The demon crouched and picked up an all too familar butterfly barrette, “You mean the old owner of this? They’re inside me! Once I consume you, you’ll be happy together inside me for all of eternity!” Douma grinned, his face contorting into one of bliss, “Oh how exciting!”
Shinobu’s face flushed angrily. She was petite and frail, but hell she would still put up her best fight. She refused to allow some perverted demon fantasize about her S/O. Thus, she propelled herself forward, silently preparing to unleash a breath attack. However, before the attack could reach the demon’s body, he collapsed onto his knees.
“Heh, what is this feeling?” He falls forward, barely suspending himself upwards with his arms. His coughs echo throughout the area as his face grotesquely begins to melt. His eye pops out falling at his side with a squelching sound. “Is this that S/O’s work…? How p-pathetic..a bit of an anticlimactic end for me…”
Shinobu stood still, too shocked to comprehend the scene before her. She recollected her thoughts, realizing that S/O had had a strange collection of wisteria in the previous months. She mockingly laughed at the demon as she walked to his crouched body. She then sliced Douma’s back, once, then twice, until she noticed his body started the process of deterioration. “I hate you, I hate you, I hate you, I hate you!” Angry tears slides down her cheeks, as she haphazardly wiped them, “Why did you ruin my life?! Why did you take them away? Why—“
As if a bucket of water was dumped onto her, Shinobu was snapped out of her soliloquy. Kanao gingerly placed a hand on her shoulder, quietly asking if Shinobu could walk. Shinobu nodded, her resolve to fight returning. She couldn’t mourn now, not when S/O has given her the opportunity to defeat the ringleader. She would defeat Muzan, and give S/O the mourning they deserved.
