Headscratchers / Touhou Mother

• In Old Gensokyo, when Yuuka is interrogating Elly on what happened to everyone from Lotus Land Story, Elly clearly says that Kurumi burned away in sunlight. Later, you encounter Kurumi conspiring with some guys. Huh?
• Why is it that when Reimu is affected by any status ailments that involve PSI, she can still use powers because “Reimu uses Bombs, not PSI!”. Isn’t it a PSI attack regardless? Or did I miss something in the game?
