The Orb Boss, who in game is named Orb Holder Yoshikage, is a neon red reskin of Yoshikage Kira. However unlike Kira, it only uses a barrage and a roll. It has a impressive 796,000 HP which is the same as normal Kira's. The Orb Boss is also the only known way to get the Shiny Red Orb item, it is unknown what this item does but the drop rates for it are very low. Estimated to be 1% or less. This Boss also drops many of the in game orbs, including the Shadow Orb, Flushed Orb, Bruh Orb(not sure bout this),,Cracked Galaxy Orb etc. In order to fight this boss you must talk to the Mysterious Orb NPC, after the dialogue is over it takes up to 15 seconds to be teleported to the Orb Boss Arena. Which is filled with neon red rocks and a massive throne at the end. Also if you see on the ceiling, it appears to be glowing red neon eyes.
(Can someone who knows what they're doing fix this page up? Thanks.) Also if the red orb is real, Then the chances of it dropping are VERY LESS
