Moonlight Temptation Trophy in Bloodstained: Curse of the Moon

Story related and cannot be missed.

You must beat the first stage, Moonlight Temptation. You have only Zangetsu to use in this stage when starting the game or playing Ultimate. There are no upgrades in this stage.

In Nightmare mode, there is a bonus life upgrade by climbing the stairs at the beginning.
 

To defeat the first boss, Glutton Train, wait until its hand grabs the rear platform and drags it towards the main body. Climb on the platform and hit him in the gold mask. Climb on the rear platform to avoid his blast attack, and use a weapon to destroy falling fire balls when they hit the ground so you’ll have a place to stand.
 

Most bosses in the game have a desperation move. Once they are defeated, they will attack you with a big attack you must survive before the battle truly ends. The desperation move on this boss is to fire a massive beam, but there is a safe zone to avoid any damage.
 

Upon beating the Glutton Train, you have the option to recruit Miriam, the star of Bloodstained: Ritual of the Night into your team. To recruit her, press to talk to her when close by.

Recruit Miriam as part of Those Left Behind or Blade Gleaming at Sunrise
Kill her as part of Emperor of Darkness
Ignore her and move right as part of Nightmare's End
