Does anyone know where I can read the raw?

Riding this do I can know too

Haven't found a site that shows all available raws but I found official Japanese websites that let you read the first and latest chapters. Most official Japanese websites I found required points.

This site lets you read chapters 1.1-1.3 and 8.4-8.5.

This site lets you read chapters chapters 1.1-1.7 and 8.1-8.4.

However, based on this site, the latest is chapter 9.1 but this site requires points.

They seem to upload new chapters every 2 weeks so you can check every two weeks to read the latest chapter for free. But the older chapters will eventually become unavailable to read for free after a new chapter is uploaded so better to read what you can read while it's still free.
