Hi there ! I just searched the forum but I could not find anything about Mary's Blood. I dont have much information about them but I would like to other meet SH members who likes them and I would be really glad If someone tell me things about them or anyone checks them in this post and likes them. 

Here is some of their songs;





and here is their guitarist Saki san <3 (they play in different genres than mami so she is my number 1 japanese metal guitarist)

You can find shortclips from their songs "Counter Strike", "Bite The Bullet" and "Moebius Loop" and any Clips from Sakis guitar soli to other songs.
Sorry but i must weiting 7 days for posting links.

The drummer has played for bands like Clandestined and Cruciefied.
Any Songs from Mary´s Blood like "I`m Dead" and "Veronica" shows very high speed double based blast beat songs and very thrashy. Yes the fastest thrash metal songs I have ever heard. They overbites bands I have heard 25 years ago like Slayer, Kreator, Pestilence, Sadus, Infernal Mayesty, Destruction, Violent Force, Devastation, Sarcofago... so those bands were still good.
