Okita Sougo from Gintama. His female version (Souko) is also reviewed on this site.
There are two versions of Okita from Megahouse and few more from other vendors. I find this one to be the best among them because this is the most normal Okita you are going to find in high quality.
The quality of figure is on par with Megahouse Toshi. The shading is identical which makes displaying those two together a bliss. Okita is considerably short however due to his pose.
The box also comes with an additional arm with a bazooka and another head with a eye-mask and a grin. The optional parts make the figure look far more relaxed, giving you a choice between a serious aura and a relaxed aura. Those are good options. I opted for the default (serious) look for my display.
The bazooka cannot be taken off by the by.
