He is the artist behind the popular manga like Galaxy Express (银河铁道999), Battle Spaceship Yamato (宇宙战舰大和号), Captain Herlock (宇宙海盗王哈罗克) and others.
I think Matsumoto-san designed this pen based on Captain Herlock.
What do you think?
I believe there are plan to release other color edition too in the near future, and more details can be found on Sailor Japan web site.
The Montegrappa launched DC superhero edition pen. Sailor launched manga edition pen. I wonder who will be the next pen maker to launch the Marvel super hero.
