Saigo no Nindou / Ninja Spirit clean artwork used on the arcade flyer and the cover of the Game Boy release in Japan.

My attempt to restore the artwork of #SaigoNoNindou / #NinjaSpirit used on the arcade flyer and the cover of the #GameBoy release in Japan. Used different sources to fill missing bits, removing text/logo, and applying the usual upscale/clean/retouch combo. No clue on the artist.
