Linked Horizon

Instagram isn't official for Linked Horizon; Sound Horizon's attention page notes there are no Linked Horizon Instagram accounts, so the public updates you’ll find come from X via L_Horizon_info. To get hooked, start with the Attack on Titan openings Guren no Yumiya and Shinzō wo Sasageyo!, and check the 2024 best-of Attack on Memories that added a new track. L_Horizon_info remains the main public hub for Linked Horizon news, while the pasted Instagram handle appears to be fan-run rather than official.
