[Tokyo Avengers] the Big Sister of the Venue Is the Ceiling of Combat Power

What will happen when there is a strong and CP-eating eldest sister and sister-in-law at the venue? The writing is not good, please forgive me. The protagonist has a CP, and they are all self-designed characters. The protagonist and CP are both female. If you can't accept it, please give up. I'm sorry. It's a short article... Right? Update from time to time, more comments, the author will be motivated ~ Not recommended for fattening 1111111111111111111111111111111111111111111111111111111111111111111111111111 Copywriting Scene 1 Haozhe: I am Keisuke-chan's eldest sister! Everyone in the East: You still have a sister at the venue! ? Keisuke Chichi: She is the half-sister... Scene 2 Haozhe: I am Keisuke-chan's eldest sister. Since you are his friends, you are also my younger brothers. I will protect you if anything happens! Dongsuzhong: Hello, eldest sister! Hao Zhe: By the way, this is my girlfriend, and she is also your other eldest sister. You can call her sister-in-law~ Dongsuzhong: We still have a sister-in-law! ! ! Venue Keisuke: Sister! Why didn't I know I had a sister-in-law! ! ! 111111111111111111111111111111111111111111111111111111111111111111111111111 The world setting of the two protagonists: the mother of the venue was originally married to a Chinese and later divorced due to certain things. The protagonist is Zeng Yan who went to China with her father and met there. Then the mother who came to the venue remarried and gave birth to the venue. So the protagonist's last name is different from that of the venue, so please don't worry. The protagonist is two years older than the venue. The venue is 175cm tall, the protagonist is 185cm tall, and Zeng Yan is 183cm tall (The height reflects the style of a big sister, hehe~) Because the author is still a novice, I hope you can comment more~ cp: Haozhe ⅹ Zeng Yan, Keisuke ⅹ Chifuyu... [There are several of them, see for yourself, the official match is not divided] Intention: Young people have their own teenage madness!
