After re-reading Osorezan-Revoir (Now that I read the latest SK chapter and side stories I understood a lot more then couple of months ago when ATT released it) I have some theories on the Origin of Reishi and Anna and Hao supreme power, so here it's goes.

First of all my theory of the Reishi ability is that it's actually a demon power required by having demon inside of you (like the case of Anna and Hao), what made me think that is Hao only had the ability after he merge with Ohachiyo and they indeed called it 'Demon Power' (although they also called Oversoul demon power so I put that aside), and in the latest chapter when Opacho join Yoh and Co. to meet Hao, Yoh saw vision of Ohachiyo when he found out Hao gave the Reishi ability to Opacho as well. Also Anna lost her Reishi ability and she herself don't know why, my guess is that when she decided she can beat the Oni inide her after Yoh defeated OhOni and when she was able to defeat it (in other words to overcome it all) it disappeared with the Oni.
Now about the connection with the Onis and Reishi ability, Oni actually made from the dirty thought and feeling of human as you can see in Osorezan-Revoir and also as you can see in Mappa-Douji Ohachiyo stated Onis are also human who did bad stuff in their life and full of dirty thought, now if that true that Oni need those bad though and all to exist(Actually I saw different types of Oni in the SK world, so It's not the same for them all) the Reishi ability is great source of it like the case with Anna (and Hao althou he controlled the Oni unlike Anna because he was actually friedly and made him understand human[the Oni not Hao ^^;;]).


Now about Anna and Hao great powers, like Matasamune said 'The power of the Shaman is the power of the heart' (it really was said a lot of times in different way so no need for me to write about this) and like what Yoh said after he and his friends trained in hell and comment Hao trained 900 years in Hell so they still no match for him 'Mabye the 100 years Hao was alive was even worse then the 900 years in Hell' (which I GREATLY agree with as Hao have such weak heart, and the all story with Matasmune betraying him), so Anna and Hao who overcome so much and probebly don't put doubts in their heart so much ought to become really strong, I have more to say about this but I'm exhausted, first time I actually write more then 5 lines (and the fact it's 3am).


Now all of you who actually read it all (I know I wouldn't) probebly ask what the point? And why did I made you read so much….well….I have no idea…sorry^_^

Oh yeh all comment, flames, and 'You stupid asshole you got it all wrong' and 'This is just pieces of shit' (which I actually think that's what I will think after good sleep) are welcome^_^
