Ichigo kurosaki is
Ummm i believe it is either Zangetsu or Tensa Zangetsu
It is Zangetsu
ask youtube
It means (slashing moon) cutting moon Zangetsu means Cutting Moon/Slashing Moon/Slaying Moon
Yeah he fought Tensa Zangetsu for a little bit and then fought HIchigo and Tensa Zangetsu combined
You will find the beginning of the fight with Tensa Zangetsu in episode 302 and guess you could follow the to be continued form there. Hope my answer was helpful. But does anyone know where Grimmjow fights Ichigo in his released form.
Yes.
Eventually
Ichigo's Zanpakuto is called Zangetsu.
The best place to find a Tensa Zangetsu replica is trueswords.com. It is about 63' total, from the tip of the blade to the bottom of the hilt. This sword is beautifully made and is almost exactly like the sword from the anime. trueswords.com/ichigo-bankai-sword-inspired-anime-tensa-zangetsu-p-2556.html
if you mean the spirit the spirit is either in ichigos head or turns into the sword. if you're talking about the sword itself the original zangetsu (from rukias power) broke while ichigo was fighting byakuya. then it became weak. ichigo then under went training with urahara and ichigo recieved a new stronger zangetsu.
It's a random card drop from the machine.
