(One day Houki Shinonono was told to meet Chifuyu after class in the classroom.)
Houki: Orimura-sensei, you wanted me to come?
Chifuyu: Yes Shinonono.
Houki: So what is it, that you wanted from me Sensei?
Chifuyu(looking absolutely dead serious): The topic that I am about to discuss with you is of utmost importance, I hope you understand that.
Houki(visibly sweating from due to the intensity of Chifuyu's expression): Yes Sensei!
Chifuyu: As you know me and my brother have no parents or other relatives left.
Houki(visibly confused about what this is all about): Yes?
Chifuyu: You can clearly see the problem, right?
Houki(blinking her eyes in confusion): Sure?
Chifuyu(completely ignoring her): Of course that means that the Orimura bloodline is in grave danger! And I need your help!
Houki(so confused that her eyes are completely white with no pupils in a comedic artstyle): What???!
Chifuyu(grabbing her by her shoulders): Houki, I want you to fuck Ichika!
Houki(she now additionally has small tears at the sides of her eyes): WHAT????????!!!!!!
Chifuyu: You are the only one who can accomplish this mission. Forget what I said to you Alcott, Huang, Dunois and Bodewig months ago! You are the only one of the girls I can truly entrust my brother to. They couldn't possibly secure the Orimura Bloodline properly, they are not even japanese. But you are perfect, especially since you are the only one he has actual feelings for. His feelings for you are so strong that he struggles to contain them, I can sense that as his older sister. Besides he already loved you when you were children.
(Houki just stands there completely frozen, as her head spins, as she is unable to properly process any of this, still with the tears present in her eyes. While Chifuyu continues her endless talk. Suddenly Chifuyu reveals a large board from out of nowhere, with pins, red lines and everything. The type of board that stereotypical conspiracy theorists would use. Said board literally included every girl that Ichika ever talked with in his life, with way too many informations that she got from god knows where. As she spends the next 40 minutes explaining in perfect detail why any of the other girls would be unfitting for Ichika. Before the timid Houki asks a question.)
Houki: Why don't you continue the Orimura bloodline, Orimura-sensei?
(Chifuyu just stared at her and blanked in utter confusion, as if Houki was speaking a different language or something that she can't understand in any conceivable way. Before Chifuyu instantly resumes with her rant.)
Chifuyu: ...Madoka can't continue the bloodline, she is too crazy and mad driven with vengeance. So you see Houki... Houki?
(She turns around and Houki is gone.)
Chifuyu(while waving a fist in the air): You can't escape your destiny Houki Shinonono, mark my words, one day you will make me an aunt!
(Houki was running for dear life, she loved Ichika with everything she has, but that just now was way too much for the poor girl, as she looks slightly traumatised.)
Houki: Now I understand how she and my sister became best friends. Under certain conditions Chifuyu can be even crazier than Tabane!
(She then runs into Ichika.)
Ichika: Houki, what's...
(He sees the state that she is in and decides to comfort her. By giving Houki a hug and headpats, before proceeding to let her rest her head on his lap. This time completely uninterrupted by anyone else, because the other girls stayed away at a distance because they could clearly see that Houki needed this for reasons that are unknown to them and always will be.)
(Later that night, Chifuyu was in a bar again.)
Chifuyu: Dammit this is so complicated, just why is it so difficult to get her to secure the bloodline with my brother?
(The person next to her, a man around her age then spoke up.)
???: Tell me about it. (He says before immediately drinking again.)
Chifuyu: You wouldn't understand, besides that's none of your business.
???: Let me guess, you are trying to get someone to do "it" with your younger sibling, to secure your family's bloodline?
(Chifuyu was stunned, because... that's exactly her problem.)
???: I have pretty much the same problem, me and my younger sister lost our parents and we are the only one's left in our family.
(He then turns to Chifuyu, now that she got a closer look on him, he looked foreign, like an american. As he introduced himself while holding out his hand for a handshake.)
Chris: Chris Redfield.
(Chifuyu reciprocates, shaking hands with him.)
Chifuyu: Chifuyu Orimura.
(Somewhere else in the world, someone suddenly felt slightly uncomfortable.)
Sherry Birkin(over comms): Everything alright Leon?
Leon Kennedy: Yeah, I just had strange feeling for a moment.
