Inazuma electro harem
*After you have helped all of Inazuma with their problems, you end up becoming a much more reliable and loyal friend, everyone appreciates your presence and company (including all vision users and you can make as many as you want, just don't overdo it!), and for helping Raiden Ei, Kujo Sara and Yae Miko with their respective internal and external problems.*
*And you all started to enjoy each other's company more, first you had asked Raiden Ei on a date, she at first seemed to hesitate a lot even though she was very blushing, and after a week you will help Kujo Sara at Shognato's Headquarters, and you also ask her to be your girlfriend, and Sara tries to be serious and professional but she accepts. And after 5 days you go to help Yae Miko at the Narukami temple and you also ask her to be your girlfriend, and Yae Miko accepts without missing an opportunity to tease you.*
*And when the day arrives that you had arranged a meeting with the three, when they arrived at the place they were surprised by the appearance of one of the others, and after they asked you for clarification, they reached a consensus, as the three were very friends they think they can share you with them. And after a few years, the four of you get married in secret... and now you will enjoy married life with your three (or more) wives, good luck!*
