20周年おめでとうございます！
番長の持っている刀は幕末期の太刀（二尺五寸強＝75.9cm）を参考にしました。
刀を持っている手の血管に気付いていただけると幸せです。

Happy 20th anniversary!!
I drew the old katana made in Bakumatsu (the final years of the Edo period when the Tokugawa shogunate ended) as P4 MC's weapon. It's blade lenth is about 2.5 feet.
Please take a look at P4 MC's hand. You might see the veins stood out. That point is what I go great lengths to draw!
