Today's anime fans love Bleachas an iconic shonen series that helped inspire the likes of Jujutsu Kaisenand Demon Slayer, but even Bleach needed its own inspirations. If fans rewind things back by one generation, long before Tanjiro or Yuji ever fought a monster, fans will see how author Tite Kubo got inspiration for his supernatural monster hunter series. To begin with, the whole idea emerged from Mr. Kubo's desire to draw a blade-wielding grim reaper in black robes, hence Rukia Kuchiki's genesis at the start of Bleach's creative process.
