I, Kamijou Mayumi Eighteen years old, a beautiful young girl The center of a popular idol group, good at singing, dancing, rap and... Sorry, not basketball I am a single-parent family and have a very bad relationship with my father, but it is said that he is getting married soon, and his partner also has a son who is two years younger than me? When I went to visit the legendary brother-kun with the mentality of "we always have to treat each other as brothers and sisters, it's better to establish a good relationship early"... He flew up to the sky in a Gundam good Very good very good It's a magical plot that even movies dare not film. If Japan is destroyed tomorrow, my brother will definitely have a share of the credit. ========== A voice suddenly appeared in Kamijou Mayumi's mind. It called itself the system and asked her to listen to it. Kamijou Mayumi: Okay, Tou-chan, what do I need to do? System: You want to be a great hero and save the world Kamijou Mayumi: I'm already saving the world System:? Kamijou Mayumi: You see, the fans who participated in the handshake meeting all cried and said that I was their savior. ========== System: An unknown monster has been detected in the southeast. Please go to the host to eliminate it as soon as possible. Kamijou Mayumi: Monster? Oh, can you wait a few hours? I'm going to shoot the cover of a fashion magazine soon? System: Strong negative mood swings are detected nearby, and a witch will invade. Ask the host to help the magical girl destroy the witch and save the residents Kamijou Mayumi: Sack! The concert is about to start, I'll go after it's over! System: Detected—— Kamijou Mayumi: This commercial will be filmed immediately! System: ... Host, are you actually here to destroy the world? ========== Kyubey: Sign a contract with me and become a magical girl Kamijou Mayumi: Do miracles and magic really exist? Kyubey: It exists Kamijou Mayumi: That's great. Can you help me kill the system? It calls me to save the world every day, so where do I have time? Kyubey:...... Kyubey: Sorry, you don't have enough qualification balance to become a magical girl. ========== Miki Sayaka: Kamijou-senpai and Kyosuke... Mayumi Kamijou: Not every Kamijou is related to your childhood sweetheart, right? ========== Orikasa Sento: Long time no see Kamijou Mayumi: Indeed, long time no see Haruhara Momose: Huh? Do you know Chi and Kamijou-san? Kamijou Mayumi: What are you talking about? Momo, Sen has slept in my bed? ========== Lost Horse: Do you want to drive Dynazaon and save the world? We are looking for driver replacement Kamijou Mayumi: No, I don't want to, I don't have time! Try something Mainly DYNAZENON, let's take a look at Ai Nana and Xiao Yuan Lian (the span is so big, why is it so sticky?) Don't dismantle Pengya, don't dismantle Lefang, don't dismantle Youli, the rest depends on your mood CP has a high probability of choosing one of Li Ge and Shen Di, but the possibility of falling in love with Nana cannot be ruled out. The supporting role column is an alternative. The main plot and timeline follow DYNAZENON The heroine is scornful and salty, and she only cares about money. Those who are not feeling well should be careful to avoid lightning. Don't leave it open until the refinement is complete, eh Intention:.
