Status Updates From ランド 1 (Land, #1)

These are 3-in-1 volumes, but since there are 11 volumes, which omnibus gets the short end of the stick and only has 2? I don't know which volumes to mark I've read. So I guess I'll translate the summaries on here and try to figure it out from that. Unless they all have the same generic summary...I hope not or else this will get very confusing.
