First normal 1CC (non-default lives though) and it's... Lotus Land Story ReimuB? And only my second or third serious LLS normal run (I'd already 1CC'd Easy)? Yeah, I don't know either.

For the record, I have no idea what anything in this screenshot means. :V (EDIT: Found out. Apparently the numbers are as follows: score, deaths, bombs, completion percentage, kill rate, items collected, items collected above POC, focus ratio, slowdown, grade.)
Either way, I consider that to be the moment when I ceased to be "a guy who plays Touhou" and became "a Touhou player".
I've been grinding away at IN and have been in a bit of a rut, and I wanted to get more practice with shot types that aren't homing-Reimu, so I decided to do a complete tour of the series: SoEW through TD, every shot type, one credit each, see how far I can go. Suddenly, bam, LLS 1CC.
Interestingly enough, I had just whiffed a ReimuA run at the last possible second (seriously, stage 6 Yuuka's health was
in the red) - which, for some reason, the game entered in to the high score list as an All Clear anyways? Again, I got nothing.
(this did not prepare me at all for the ass-whooping I received when I attempted Mystic Square)
