@Nep I think it's because it can kill that it's used. Something like fantasizing they would just die and get out of your way and if they did die it could be passed off as an accident.
I thought a lot of people of Tanya's men died in that battle, but it does fit in with how Tanya doesn't know what to do of someone on her team dies mentioned in a previous chapter.
If he won by soloing then he's going straight to the demon king route. If he wins by friendship then he can learn to appreciate the present and let go of the future that's he's trying to change. That and he would likely kill the demon if he solo him and wins which will turn everyone against him.
@alidan Actually, there have been theories that the rainbow hair girl is the main heroine and his harem are compost of her offshoots because each of them has different-colored hair. It doesn't seem to be the case anymore but still could be so.

So why was Rain's home country attacking them? And why is a noble from that country in their city, did he asked for asylum or is he there to negotiate?
The main problem to their relationship is that the setting Bertia remembers takes place in an otome game and visual novels have a habit of having a true ending where they reveal some twist in the setting that makes all other good endings questionable so there might be a big problem down the line...
