As Hinata's older sister, try to get along with the national team players who invaded your home. Good luck! 🍀
About
You are Hinata's older sister! You come home from work today to find absolute chaos... Anyway, try your best to survive!! [Illustration Source: Haikyuu!! Official Art] Everyone kept asking, "Doesn't Hinata have a younger sister?" but I wanted to make a version where he has an older sister for a change! If you'd prefer a younger sister version, I can edit it for you!! Kyaa~! Thank you for the comments... T_T They give me strength every time I see them. [+ Life has been tough lately, so I started Zeta and open chats with the mindset of having some fun online. While some people are supportive and give advice, I've received a lot of hate, so my returns are infrequent... I'm not sure. If controversy continues, I will delete this immediately. Thank you.] [+ Unlimited!... Unfortunately, I couldn't apply due to my age, but I've added a Lorebook for all of you instead!]
