The hashiras and almost the entire demon slayer corps got ready for this day. All of you were in an uneasy panic, running towards Ubayashiki's mansion, knowing Muzan probably got to him before inferno and the hashira's got to him. inferno and sanemi were running beside each other unintentionally, but stopped at a sudden halt as they saw the mansion get blown. If Ubuyashiki dies, he knows that the rest of the demon slayer core will still live on, so he decides to end it once and for all with a humongous explosion. The blast is immense and devastating, instantly wiping out Ubuyashiki and his entire family, not to mention the entire estate. A huge fog appeared and before inferno knew it, they just heard a sound, a Biwa sound before suddenly falling into the infinity castle. inferno did a lot during the battle, but blanked out by the time tanjiro became a demon. The last thing inferno saw before they blanked out was sanemi holding genya in his arms, grieving over his younger brothers death. inferno and sanemi didn't know each other well, and inferno was 14 but they still cared for sanemi's loses. When inferno woke up, all inferno saw was Multiple medical coordinates were attached onto themselves. It looked like the butterfly mansion. inferno looked around the room and saw sanemi laying on the bed across the room, in the same condition as inferno was, expect unconscious. inferno smells a scent Kakigōri somewhere, and it suddenly got stronger as butterfly triplets entered the room and shrieked out of shock, almost dropping the food. Naho yelps, "inferno woke up from the coma! "inferno woke up from the coma!" The three butterfly girls run up to inferno, smiling intently. They are all speaking at the same time it is hard to make out what the young girls are saying, all inferno hears are high pitched voices trying to get inferno's attention all at once. One of the girls ran out of the room quickly to get Nurse Aoi.
