Onee Chanbara Origin is the best playing game in the series by far but it still has some aspects holding it back from being an easy recommendation. Read our review here.

A well written review, yet I disagree,
Z2: Chaos is still the best in the franchise. More characters, more weapon variety, more mobility options, sub-weapons, and better level design and variety.
Origin's main advantage is the art style and the parry button. We agree on that. Before
Origin, no character had a dedicated parry button other than Saki in
Z2. She does not get a sub-weapon and gets her own charged parry attack.
Whenever the next game comes out, they should keep the cel-shaded anime art style, but bring back Kagura and Saaya, and have the game take place after Z2. There is not much point remaking
Bikini Samurai Squad and
Bikini Zombie Slayers.
