"Did you beat So-tan in a game of chess?" Instead of answering Kisuke's question, Serafall asked a question of her own.
Kisuke started thinking what her words mean and answered, "I did."
"And So-tan probably made a fuss over her loss." Serafall looked over at Sona who started fidgeting with a flushed face. Sona is now enduring everyone's gaze in addition to Yoruichi's mean gaze.
"... You're right." Based on Serafall declaration on marriage and the current trend of the talk, Kisuke already has some clue on what's going on but he still needs to hear it completely before jumping into a conclusion.
"Did you know that a few years ago that a certain young Devil, to avoid being engaged to someone she doesn't like announce and swore to her name that she would only marry those who beat her in a game of chess? Many young men from different backgrounds tried to beat her but no one succeeded." Serafall picked up a cookie and happily ate it, 'Not as delicious as Sona's sweets though.'
"... I see... So you're saying that a young man like that appeared?" Kisuke was now sure of what's going on and looked at Sona who is now staring at the floor not daring to lift her head.
"That's why I'm here." After some cookies, Serafall calmly sips some tea.
Serafall didn't speak any further and waited for the latter's reply.
A strange silence took over the room. Sakura is blankly looking Sona and kept thinking, 'Another daughter-in-law? Not that I'm against it as like Sona-chan quite a bit... But Kisuke grew up in human society and he already has Yoruichi... Even though he's a big pervert, I doubt that he'll agree.'
Yoruichi sighed as she already knew what would be the result of this. She is sure that Kisuke will reject this marriage but she also knew that Sona wouldn't be able to take it well.
After a few more seconds of silence, Kisuke smiled and said in a jovial tone, "Hahaha... No way. It's Kaichou here we are talking about. Even if I beat her in chess, she wouldn't want to marry someone like me~. She even tried very hard to defeat me. Though she failed, her perseverance to defeat me is a testament to her resolution not to marry me. Why would even Kaichou like someone who's only a pervert and kept harassing her? We are not compatible at all~. And besides, she already knew that I have a lover and would never..." In the middle of his awfully long rejection statement, Kisuke stopped speaking as he saw Sona looking blankly at him with a neutral expression and slightly open mouth... while large amounts of tears gushing down through her face.
Serafall's eyes widened in shock. Sakura also has the same expression as her. And Yoruichi used one of her paws to cover her face, 'Kisuke, you idiot! That's too much!'
"Eh? What this? Why am I crying?..." Sona noticed her tears gushing out after a few seconds and tried to wipe it away but just as she did, her face would be drenched again by its nonstop flow.
"... Strange... My tears won't stop." Figuring out that wiping isn't enough and all of them are still staring at her, Sona tried just to laugh it off.
"... Did I got cursed without me noticing?..." But that also failed as her expression slowly contorted, "Uuuu..." She knew she couldn't hide it anymore so she stood up hurriedly without regard to her manners, ran towards the door and only left a few strangely heart-wrenching words, "... I'm sorry..."
"Sona-chan!!!" Serafall also stood up and chased after her. But before she leaves entirely, she gave Kisuke who is still dumbfounded a complicated glance.
Yoruichi jumped on the head of the startled Kisuke and scratched the bridge of his nose.
"...Ow..." Kisuke unenthusiastically reacted.
Ignoring his reaction, Yoruichi asks, "Aren't you going to chase after her?"
"What for?"
"Yep. Chasing after her is a bad idea if you have nothing else to say. Wait for a few more days before approaching her. Anyway, How does it feel to witness such a cry?"
"...Terrible... I'm not a fan..."
"Is that so?" Yoruichi jumped down and approached Sakura who wanted to say something but stopped by her, "I'm going to the training ground to look after the kids. You can go take a small walk by yourself."
Kisuke let out a large sighed and stood up, "Thanks..." And disappeared from his position with the use of Flash Step.
"Is that alright?" Sakura asks worriedly.
"It's fine. At a time like this, it's better for him to think on his own. It's his specialty anyways." Yoruichi transformed back to her human form and shrugged her shoulders.
"... You sure do know a lot about him... A lot more than I do... Are you his mother?" Sakura couldn't help but feel jealous.
"Ahahaha... I could fill the role."

After gaining some distance from the Urahara household, Sona used teleportation magic to directly appear in her room at her mansion situated at the corner of the Kuoh Town. Sona jumped to her king-size bed and covered herself with a thick blanket. Sona kept sobbing and sniffling. Serafall followed after her in worry and arrive beside her bed.
"... Sona-chan..." Even the usual cheerful mood of Serafall was gone without a trace. She didn't know how to comfort her sister as this is the first time she saw her beloved sister being so helpless. But somewhere in the corner of her mind, she felt a small relief that Sona can still act like this, not the emotionless robot that she kept portraying at home to show the dignity of the heiress of the house, 'But what will happen now?'
As Serafall paces around thinking of the words she could say, Sona's voice resounded under the blanket, "... Nee-sama... *sob* *sob* Why... why does it hurt so much?"
Serafall stopped pacing around and looked at the bundled up Sona and heaves a large sigh. She lay down beside her on the top of the blanket and patted where Sona's head would be on the blanket, "I don't know... I haven't experienced it myself."
"... Nee-sama... This feeling is very strange... *sob* *sob* I've endured much more intense words from our elders jeering at my dreams which is supposed to be the most important thing for me. Their words hurt, but I can endure it and move forward... But why do a few simple words of rejection reduced me to this state *sob* *sob*"
Serafall continued patting Sona's head and didn't say anything. It's not like she has something anyway.
Sona suddenly gets out of her cover and faced her sister. Serafall felt the need to attack the Heavens when she saw her face full of tears and swollen red eyes, 'Dammit, Ki-tan!'
"What should I do, Nee-sama!? I don't like this feeling! I want to forget it! I hate myself for thinking that maybe we could be together! Uwaahhh!!!" Sona wailed loudly as she asks her sister.
Serafall grabbed her and hugged her, burying Sona's head in her bosom, "Just cry it all out. You'll feel better later... (I guess)"
"Wahh!!! Uwaahhh!!!" Feeling the warmth of her sister enveloping her, Sona didn't stop herself from letting it all out. She has the same thoughts as her sister. If she can let it all out now, maybe she'll forget about it later and go back to her normal self.
On the top of the mansion's roof, Kisuke heaves a large sigh and disappeared.
