Umineko is unlike anything else you will ever read. It is hard to recommend due to its length, often poor pacing, and number of content warnings (read: it contains every cw known to mankind), and yet it is my favourite VN of all time.

My advice for anybody on the fence about reading Umineko:

1) Read Umineko
2) Go into Umineko as unspoiled as physically possible
3) Engage with the mysteries it presents you and you will be rewarded far more than reading it passively
4) Without love, it cannot be seen
