Since my original language isn't english nor chinese, I believe I should be the herald to translate the chinese... into broken english, yeah ok, I believe that covers the introduction, i'm sure they will get translated eventually... probably... maybe... we can hope.

All the achievements shamelessly spoil you, but i'll try to hide some spoilers just in case.


Tenshi's Peaches: Reportedly rather delicious. Never leave home without some (on your head).
Method: Kill a monster... or in other words, just beat any small enemy.


Keystone: A massive floating rock, symbolic of the power of Tenshi.
Method: Defeat White Tenshi for the first time.


Punk Rock Guitar: Not sure when did Mystia learn to play this.
Method: Get the first magic fragment. As in, the things for Byakuren, there are 3 of them in every level.


Frozen Watermelon: Watermelon on a stick, frozen solid by some idiot. Entirely refuses to budge when bitten.
Method: Defeat the first boss: Cirno.


Drunkard's Gourd: A bottomless gourd filled with sake. Must-have for striking it rich.
Method: Defeat the second boss: Suika.


Black Tome: An ornately bound magical tome.
Method: Defeat Black Alice for the first time.


The Leg of Fusion: Looks like a cast, but actually is entirely made of cement with which to seal Utsuho's powers.
Method: Defeat the third boss: Kokoro.


Maid's Knife Holder: Contains a number of razor-sharp knifes. Not sure why they're needed for housekeeping...
Method: Defeat Black Sakuya for the first time.


Messenger's Shawl: An almost weightless shawl.
Method: Unlock (buy in-game) 6 characters for your party.


Spear of Gungnir (sic): The name of Gungnir symbolizes tremendous power.
Method: Defeat the fourth boss: Remilia.


Kannushi's Hat: Apparently known as a Zun hat to the outside world.
Method: Defeat Nue.


Moon Rabbit's Tie: Favored by moon rabbits everywhere. Comes standard with a carrot tie clip.
Method: Defeat Clownpiece.


Stick Wielding Great Power: Uncontrollable power is equivalent to no power in the first place.
Method: On Stage 10, take the shortcut and defeat the 3 black fairies.


Moon Rabbit's Mesmerizer: Forces any under its effect to relive past memories and strips their ability to tell apart illusory bullets.
Method: Defeat the fifth boss: Junko.


Anti-Youkai Gohei: Apparently intended as a poking implement.
Method: Defeat the sixth boss: Reimu.


Pale Ying-Yang Orb: Just another piece of original work.

Shanghai Alice: A doll that doesn't exist in Shanghai, yet retains the power to induce fantasies in others.

Black Ying-Yang Orb: Just another piece of derivative work.

Camera: Can't possibly forget this when going to a convention.
Method: Participated in not!comiket. (Black route ending)


Umbrella Youkai: Lick.
Method: Get 24 skill upgrades from Kogasa.


Buddhist's Hat: Clearly a hat worn by one versed in buddhism. Namo western utopia. (Translator: I don't even know what that last bit was intended to mean, but as written this is the best I can do.)
Method: Get all the magic fragments for Byakuren. How, you ask?


Hakkero: An unfathomably potent magical artifact. Firepower is justice!
Method: Clear the game on Lunatic.

Well, that pretty much covers all of them. Feel free to tell me if I missed something or did a dumb typo.
Special thanks to Ariel Timeshrine for adding the flavor text for the achievements.

Hope you do the Lunatic one.
