Search まんが on google and then you can choose which site suits your taste (or in your case, where the manga is available HAHA)
Mmm... Maybe you can try buying the kindle format? It's around 7$ on amazon https://www.amazon.co.jp/%E9%8C%86%E3%81%B3%E3%81%9F%E6%9C%88-%E3%82%B7%E3%83%A7%E3%82%B3%E3%83%A9%E3%82%B3%E3%83%9F%E3%83%83%E3%82%AF%E3%82%B9-%E7%A0%82%E6%B2%B3%E6%B7%B1%E7%B4%85-ebook/dp/B00FZGYTQA/ref=tmm_kin_swatch_0?_encoding=UTF8&qid=&sr=
(Funny enough, the paper copy is way cheaper, but unfortunately the delivery charge would be too expensive)
thank you both!
are there any sites that have japanese mangas in japanese uploaded for free? like how there's t**nkor for korean manhwas?

i'm looking for "錆びた月". i'd buy it, but it's too expensive (around $20 for 1 volume that has only like, 6 chapters. worst part is, it's part of a trilogy )
