Outside of the hotel.
"It's my time to shine," Oreki said while trying to look up to Maya but all he could see was her twin peaks. Currently, he's in his Shota form looking up to Maya, so he can maximize the Mommy energy of Maya.
Maya who where embracing Oreki's head from behind while her boobs are above his head. "Looks dangerous to me. Let me handle it and enjoy being served by Miya's Mommy energy while I deal with that."
"Oi I told you already, I'm not going to join in the band of harems" Miya retorted. Her twin sister had been inviting her to do a Threesome with Oreki ever since they met earlier and the reason that Maya gave her was that she wanted to share her happiness with her. However, that is all load of bullshit because, during the Ice Pillar Break earlier, she always goes into feral mode every time a woman from the audience praises Oreki's appearance or says something like Impregnate them or marry them.
Shota Oreki moved swiftly towards Miya before hugging her in front of her waist. He then looked up to her "You don't like me Miya-nee?" He asked while giving her the most charming puppy eyes he could ever muster. "We can do it in this form." He added.
Miya bit her lips as she started breathing like a horn dog though she quickly recovered. "Come, Miya, let the horniness consume you" Maya came with an alley hoop as she whisper sweet words behind Miya while holding her shoulders.
Oreki can smell the foul yet addictive odor coming from Miya's treasure trove.
Miya did not respond and stayed quiet. Seeing this Oreki and Maya did a fist pump. "I'll wait for your answer." He said as he started walking towards the direction of the Battle Board venue. However, he stopped as he heard what Retsu said.
"My Granddaughter is still single"
"What a sly old man," Maya said while nodding sagely.
Oreki turns around if what he hears is right. "Just as you said one big happy family," Retsu said smiling.
Oreki did not answer and just smirked at the Old Man before leaving.

Back to the BB venue.
The Tatsuya friend group watched the creature up above the air with shock and awe. They did not notice that Oreki's group of friends were already beside them watching them with amused faces. They then start a betting game on who will react or shout first to break the silence of the Tatsuya's friend group though in this betting game Miyuki and Tatsuya are excluded because they are not really affected by the presence of the 8-headed water creature.
Miyuki watched with amusement and shock at the betting session of this Time Traveling Merry group. And the majority of the bet is on Erika because she looked like the talkative one. The bets are not even money as from what she can see, they are using a plain Whirl lollipop which makes her just sigh at their shenanigans while wishing she's also their friends because her friends are too proper and prim except for Erika. She also wanted to get close to them more or to specific to Oreki and request to him if he had the ability to return her Onii-sama's normal emotion to other people or friends.
However, if he heard this, Tatsuya would say that he's happy just to feel emotion towards Miyuki. He'll not deny it because if Miyuki really wanted it to happen then he had no other choice but to accept the emotion back.
While Miyuki was musing about her own thoughts, the moment that Oreki's friends had been waiting for happened.
"Ahhh! I know this thing" And the one who broke the silence is.... Mikihiko who's pointing his finger at the creature.
Tatsuya's friends break their sight away from the Water creature as they all collectively look at Mikihiko. The DxD group also screamed after Mikiho while having different kinds of expression but mainly disappointment that their bets were off.
Miyuki and Tatsuya ignored Mikihiko's sudden shout as they looked towards the DxD group to see who won because they were curious and it's easy to see who.
Koneko who's flexing her arms like she's doing her best Mugi expression. She then started collecting this precious lollipop that was made Oreki so it's pretty obvious that this thing is whole another level compared to store bought lollipop. The group asked why he made this and it's not like they hate the lollipop, they're just curious. Oreki answers with a serious expression at that time that he wants it to be used to bait a loli. That earned him a kick from Rias.
"That was the last lollipop," Gasper said while Valerie patted his shoulder. "Sorry," the latter apologized because Gasper wasn't the one bet his lollipop but she did.
"The hell?! when did you guys arrive here?" Erika asked as she ignored the big elephant in the sky floating. She's not the only one who ignores even the others too.
Valerie turn her attention to Erika before this saying in a grumpy manner "Tsk, you made me lose the money you bitch" She meant lollipop but that's not badass enough so she didn't say it like that.
"What did you say!?" Erika shouted back while she was getting ready to walk towards Valerie and throw her hand with her.
"You heard me!" Valerie replied with a smirk. "Oh, are we going to have a catfight?" Yoruichi said while laughing loudly.
"You..." Erika was about to go but Miyuki stopped her.
"Erika doesn't get work up," Miyuki said to her before looking towards Valerie "Please don't bad mouth my friends," She said.
Valerie just smirked at Miyuki before turning her attention to her own group. "Boo!!!" Yoruichi said with a thumb-down gesture.
" They got a problem to deal with right? So why do you have to say that?" Sona asked with a sigh while also saying to Yoruichi to stop being childish. Even though she also lost the bet the lollipop is not really that important to her as she's not the foodie or candy lover.
Valerie did not answer and just shrugged.
"Don't you mean our problem which includes your group?" Shizuku said.
Sona shook her head "Our instruction is us heavy hitters are to watch and wait for him to deal with that" She said while nudging her head towards the Water creature in the sky. "But don't worry friends here will help your group to stall that," She said as she pointed to her peerage while remembering that Oreki said that he buffed this thing to help her peerage to train in advance when the time comes when the real training starts. She smiles unknowingly as though Oreki is noticing her charm and beauty.
Sona then shook her head before she looked towards Tatsuya "And he also said that don't steal his thunder and just do the bare minimum to protect your friends" Sona added.
Miyuki smiled happily as she knew what Sona meant was that Oreki wanted to deal with this thing and he did not want her Onii-sama to finish the problem swiftly which he could. "As expected of Oreki, he really is a great friend to be," She thought while nodding to herself. "Don't worry Onii-sama! You don't have to do anything to protect me, I can handle myself" She said to her beloved Tatsuya.
Tatsuya just nods one time in acknowledgment of Miyuki's instruction before turning to Mikihiko and asking what is that thing in the sky.
Tatsuya group turned their attention to Mikihko while the DxD group just sat in the audience seating to relax and to watch the show that was about to unfold.
Mikihiko explained and said that this thing is called Souryuu also known as Xiangliu is a giant snake with nine human faces that is named after the evil god of the flood, 'Kyoe' that when Souryuu appears in the land, the water would rot and ruin the soil. Souryuu is summoned by using blood as an offering via an Ancient Magic Technique called Houjutsushi (lit. doll-forming magic) commonly used by magicians from the Great Asian Union.
Once the Houjutsu is broken by destroying the Souryuu, it will have a backlash to the user since they are using their spirit to manipulate the Souryuu which also damages the user and could even cause their death. Users who summon Souryuu are aware of the risk of this magic and are willing to do this exchange to manipulate Souryuu.
"And based on the size of Souryuu, This one might have a least 9 or 10 users manipulating," Mikihiko said as he couldn't imagine a lone user manipulating this massive creature.
"So we find that user while this thing is not moving yet," Leo said but as soon as he said, One of the Souryuu's mouth open.
"You jinxed it again," Honoka said with a strained smile making Leo just scratch his head while Erika kicked him to sheen.
Juunmoji Katsuto walks in front of the group and orders them "Everyone get ready to fight"
