o3o Wouldn't stress too much on Leomon content in current version. More will be available in future with opportunities to grow affection.
There is a secret route for hackmon, but only if you win the 1 v 1 among other specific conditions.
I understand then I will wait, I hope there will be many nsfw scenes with him as I think it is very hot the thought that leomon fucks me or is fucked by me knowing who guilmon was in the past.
I don't know if it's possible—or rather, it is if you want to do it—but it would be really hot to have sex with leomon while he's in his Megidramon form, assuming Guilmon can transform into Megidramon in the future. If you want to do that, of course—sorry for the bother.
