Greetings

I have been a witness to various forms paranormial activity throughout my entire life and it was up to a few years ago that i accepted these as normal events, coincidences, or anomolies with scientific explainations. But after having an experience with a spectre of some form in Kyoto,Japan I was convinced otherwise. I was visiting a Shinto shrine on vacation with several of my friends when suddenly I collapsed, One of my friends woke me up several hours later and told me I've been sleeping soundly for 5 hours, but the person who was our host there (I don't know him but my friend does) told me otherwise. He said i was mubling in Japanese as i slept (which is akquard since i barely spoke japanese). He told me what i might've been pocessed or that this was an ill-omen. I blew it off until i couldn't sleep the next night. I was staring at the ceiling when I heard a low laugh and then I heard a voice it apparently was thanking me for freeing him from Yomi (the underworld) when I got up and whispered whos there to the wind he laughed again and told me his name was Gozu (which later I found out translates into "cows-head")I didn't quite understand and layed down an put a pillow over my head, but his taunting was relentless. I asked him what I could do to make him shut-up, and he replied that he was hungry. So i went to prepare Ramen and he said his spirit had dwindled and became malnourished in Yomi. I again asked him what i could do to make him shut-up, he told me to go outside and do a ritual (was kinda like a Tai-Chi martial arts thing) and then he said he was refreshed and so i went back in and went to sleep. I awoke later to notice my hands were covered in blood, i waas confused and ran to wash them off but it wouldn't go away. I acted like nothing was on my hands and everyone believed me (as if they didn't see anything wrong with my hands) Gozu then said that i had killed several weak spirits that were roaming around aimlessly an absorbed there life-force (like an energy-vampire I guess) But to make things simpler lets just say I'm now a very experienced ghost-hunter and paranormal detective. Yes Gozu is still with me but I've learned to repress him unless of an emergency. Kiyoraka kawa is the name of my Shirasaya blade (it's a just a normal high-quality sword but Gozu says objects can take the properties of which their adressed), It means Cleansing River and apparently can sanctify areas, exorcise areas, make ethereal things material, and calm and soothes wraithes and foul spirits. (I don't know the extent of the the sword's abilities or whether it is mearley an extension of me but what I've listed has happened on actual occasions)
Please feel free to ask me anything I may (or may not) have knowledge about. Gozu may be a spirit of Japanese origin but he has been to hell and back again. (and I have a quite large amount of experience as well)
