Help with a partial kanji character

[Jaron]

Hello NMB,

 

I originally posted this in the Nihonto section as I forgot this was here. My apologies. Any thoughts would be greatly appreciated.

 

Hello NMB,

 

I was given this sword as it is tsukare and has plenty of ware, none fatal, and it still is very much alive with a vibrant hamon and well defined nioi-guchi, tobyaki everywhere when lit up properly, very clear and wet looking, and a tight itame nagare. Boshi continues the midare pattern into a jizu/kaen that reaches up high. The hamon looks very late Muromachi Mino Sue-Seki with a rough, inconsistent sanbon-sugi pattern, very Magoroku-esque. It has a double gold-foiled habaki so it was well thought of at one time.  It looks like it was forged on the edge of explosion with all the activity.  Like a storm and see something new every time you look at it in different light. The nakago is very short from the suriage but there is about half of the top of a kanji. It looks like it could be the beginning of Kane, maybe Noshu. I’ve looked through Fujishiro, the Zuikan, and Sesko’s Zenshu as well as the internet resources, and I can’t find anything close to these straight lines with two opposite strokes up. It looks like Kaneuji did something similar for Kane bu with out those upward strokes. Maybe a province? I assume it was likely a higher end smith to accomplish all the lively activity that this has, and I was hoping to figure out this kanji. Maybe someone unknown but they did a heck of a forging effort on this when it was new. I’ll include a couple of pictures of the Kanji at the edge and a couple of sugata shots so you can see the pattern as well. It’s tired but still beautiful. I really cut these pics down so I hope they are good enough. Thank you in advance for any thoughts
