Bound to the Thunder Strategy System, I Complete Missions by Squeezing My Teammates and Defend Our Championship with Them

Note: A certain Detective Conan series has collapsed, and I no longer feel like writing it. Same protagonists, new premise. Feel free to take what you like. This blurb isn't final and may still be revised. One day, I woke up to find a mysterious voice in my head telling me to win over eligible targets. Then I discovered that one of those targets was actually my teammate, someone I saw every day? Ha! As if I'd ever try to win over one of my bros. What? You say raising their affection levels will get me a plan to improve my strength? Well, in that case, what are we waiting for? They said they could handle raising the affection levels. System [breaking down]: I'm a romance System! Why do you drag your targets off to train every day? Aren't you going to follow the main plot? Nioh: Who could fall in love with a bro who keeps forcing him to train? Only a masochist. Premise: Nothing is more satisfying than becoming stronger yourself.
