Ginjo turned his head right while taking an earbud out when he heard his brother call out to him. Upon eye contact, he saw an attractive girl that fitted Issei's description walking next to him with a smile on her face.
"I assume that's her, judging how she's walking next to you, happy as can be."
"You guessed right, little bro!" Issei answered with a wink before pointing a hand at the girl. "Ginjo, Yuuma Amano, my girlfriend. Yuuma, this is my little brother, Ginjo."
The girl, Yuuma, smiled brightly and bowed to Ginjo.
"It's nice to meet you, Ginjo-san."
Ginjo got up from the bench to bow back at her.
"Likewise, Yuuma-san. Is it alright that I call you that?"
"Of course," Yuuma replies after getting up from her bow.
Ginjo then turns his head towards Issei.
"So, did you introduce her to your pervy friends?"
Issei lets out a hardy laugh, earning a giggle from Yuuma while she covered her mouth with a hand.
"You bet your sweet ass I did, bro. And their looks were priceless!"
Ginjo laughs gently at Issei before setting his eyes on Yuuma.
"Hey, Yuuma-san?"
"Yes, Ginjo-san?"
Swallowing a lump, Ginjo began to tell her what he had to tell her.
"When you two go out on your date, please be… gentle with my brother. He can be rather hyper at some times and may do stuff he doesn't mean to do…"
"Oh, don't worry, Ginjo-san. I'll take care of him like he's my cute kitty cat!"
Issei blushes while scratching the back of his head.
"Come on, now. The only cute kitty cat around here is you~."
Yuuma giggles with a healthy blush on her cheeks.
"Aww~! Stop, you're embarrassing me."
Ginjo watches on to see the two sharing a laugh with one another. Being known as the Human Lie Detector by Issei, and his parents, Ginjo could see that Yuuma was very happy with his older brother's company. Her smile looked real, and so did her blush.
Even so, Ginjo couldn't help but feel worried for Issei. He knows how some first dates with a girl could end judging from some stories of his father's first two dates before marrying his mother, and if it ended in a way that would leave his older brother sad and depressed. And as his little brother, Ginjo did not want him to stay in that state for a very long time.
As he was thinking about this, Ginjo decided that he was going to follow Issei and Yuuma on their date this Sunday incognito, both to make sure that his brother's date goes well, and to make sure that Issei doesn't give in to his breast fetish, which he promised him he won't do while they were playing Halo together yesterday.
Meanwhile, as Ginjo, Issei, and Yuuma were still chatting with one another, a familiar petite girl was watching them while she was sucking on a cat-shaped lollipop.
'Better notify Buchou.'
"I see, are you sure that's what she is?"
Inside one of the rooms of the old school building, Rias could be seen sitting at her desk, asking Koneko for the confirmation of Yuuma's identity. Along with the two was Akeno serving tea, and Yuuto, sitting on a couch near Koneko.
"Yes, I'm sure, Buchou," Koneko confirms with a nod.
Satisfied with the information given to her, Rias nods and gives her a smile.
"Good job, Koneko-san."
Yuuto stands up from the couch, getting everyone's attention.
"What shall we do now, Buchou? We can't afford to have the two in danger, judging from what Koneko-san said about the younger Hyoudou telling her that he was going to watch the older one in secret."
Rias pondered about Yuuto's question for a moment before looking towards Koneko.
"Koneko-san, since the first year Hyoudou-kun is your classmate, I'm putting you in charge of following him this Sunday so he won't be in harm's way. As for the other Hyoudou-kun, I'll have my familiar give him a flier in case he meets an unfortunate end."
Yuuto raises an eyebrow at her.
"So you plan on letting him die so you can reincarnate him? I know he can be lecherous, but it is cruel to take him under your wing without at least letting him choose to become one."
"Of course not," Rias answers while shaking her head. "That's what Koneko-san's here for. Not only will she be following the younger Hyoudou-kun, but she will technically follow the older one as well, making sure they both don't die."
Koneko frowns slightly when Rias mentioned her following Issei. While she doesn't hate him to the point of wanting him literally dead, she still felt slightly uncomfortable about having to protect the pervert. Plus, he was Ginjo's brother, and with the friendship the two first-year students developed, she didn't want him to be sad.
~Timeskip; Sunday~
The day when Issei and Yuuma go on their date has finally arrived. Ginjo was currently wearing a blue, short-sleeved T-shirt with brown, short pants that reached above his knees, cobalt tennis shoes with white socks, and a necklace that carried a red crystal.
When his parents asked where he was going, Ginjo told them that he will be heading outside for a long walk and that he'd be back in the afternoon. After saying his goodbyes to his parents, he closed the door behind him, locked the door, and went off to find Issei.
Ginjo made his way towards the area where Issei told him that he'd meet Yuuma to start their date. By the time he made it there, he saw that Issei was wearing a simple purple T-shirt with long, brown pants and white tennis shoes. Ginjo nods at him, while at the same time keeping out of sight from him.
However, what Ginjo doesn't know is that Koneko is following him, and technically, Issei, without him noticing, making sure that they don't get hurt by the threat Rias told her about.
While she was keeping out of sight, Koneko mostly had her sights on Ginjo, blinking twice in slight surprise to see that he had a serious expression while keeping out of sight from his older brother.
"Okay," Ginjo says to himself, in the hearing range of Koneko without him knowing. "I just need to keep my distance from those two, that way, I can easily follow them and make sure Ise-nii doesn't screw up."
Koneko slightly widens her eyes at Ginjo. Him, helping a pervert not perv on his "Date"? Despite the many times Ginjo told her that there was good in Issei, she still was very wary of the older Hyoudou nonetheless because of the many times he peeped on the women changing.
"Issei-kun!"
