Read stuff on my tablet via library app or pdf at lunchtime then manga on an eink android tablet before bed.

Envato elements but its gearded towards design professionals so its stock photos is only a section of the offerings and might not have as wide a variety as you want.

Might be better off getting a regular tablet depending on the reasons you want to get off your phone. Colour eink just isn't there for comics really.

They are all easy but personally I find reading manga on any display under 8 inches quite tiring

Bit more to go so since I'm stuck on the second group of floors but thanks.

This is all good to know becuase I was assuming I would have to go through all of Maou tower too.
