We can't keep letting this relationship getting abusive by making each other wait long periods of time xD

Botan being the unforeseen third target would not only be a twist, because neither Kurama nor Botan at the time believed it could affect them like it could a basic human, it would also let Kurama be the big hero. By saving her from another incident, word might get around about it, making him a hero (which he wouldn't really want. The guy keeps to himself.) and intensifies the way people look at them. The 'rumors' start to be seen as even more truthful. If not that, then Kurama or Botan just say that they are going out ahead of time to prevent any harassment for the other party, mostly Botan.

Botan's moves, yeah. I think I remember you saying you didn't really want her to be a plant-based combatant like Kurama. He could just teach her simple tactics in dangerous situations. Botan is a bad ass survivor girl so she won't need much in the way of that training. You could let her use that ring amplifier that let Yusuke use the Spirit Gun when he first started out?

Yes, Kurama and Botan use the gardening club as a cover to not be home so early with Shiori and to get work done without being disturbed. It's also where Botan can hone her healing talents in private. I think some guys might try to join to get closer to her, which fails no doubt. 

When you say low-level demons, do you mean scrubs like little imps, or people like Rando? Because compared to Team Toguro, everything that Yusuke and the group dealt with up to that point were bottom-barrel losers xP
