Reimu Hakurei

Overview
Reimu Hakurei is one of the many bosses in-game. She can shoot ranged projectiles at players.

Difficulty
Reimu is considered to be a more medium boss, though not as difficult as Doomguy is. It's also small, making this boss harder for melee players.

Appearance
Reimu is the main character and a selectable player in the Touhou series of games. As the shrine maiden of the Hakurei Shrine, she manages a border between the outside world and a place called Gensokyo and deals with problems in said place. In-game, she has the appearance of a plush.

Strategies
It’s recommended to bring whatever you may need to fight Reimu. It really doesn’t matter though you may wanna use a Speed Coil or an EpicKatana to get away from her ranged attacks. Due to her smaller appearance, it’s recommended to try and bring explosives, more specifically the BFG 9000 and maybe Klee's Bomb.

Trivia

 * In-game, Reimu is actually a Fumo Fumo plush instead of a 3D model like Sakuya.
