HP & TRQ will always have a peak in a 4 cycle internal combustion engine,so that means they also always have an uphill and downhill slope as well.
If they did'nt,all the dyno graphs you see would all just be an uphill line.
Now granted the slopes can be really steep & peaky,or slow gradual slopes with a barely discernible peak,but the slopes are there none-the-less.
And even a perfectly flat torque curve would'nt "increase" with RPM,it would just remain the same (ie: a constant).
This all will surely just lead to a huge debate that amounts to a semantics battle royale,but suffice it to say,torque does not always increase with RPM.
FWIW
