I have been lookinng for Sakura Micron fineliners everywhere and just recently I was able to get my hands on some! I dont really draw manga but I think this set is supposed to equip you with the basic tools. I'll just be using this for bullet journaling though.
Here are some swatches:

*sorry my handwriting isnt that great lol
It comes with 4 fineliners (0.05, 0.1, 0.5, 0.8), a brush pen and white Gelly Roll.
