Its all about payoff honestly.
S1 limited time suit action balanced by Zero and Garo vs. Zero.
S3 limited time action balanced by their progress of teamwork against Sonshi.
Jinga came out underwhelming IMO because Jinga is neither had veteran aura like Sonshi nor smart guy like Tousei;
Ago OTOH is pretty acceptable since his background and motivation matched with Makai Kishi underwhelming condition implied in S3.
We haven't seen something worth the wait for Hagane.
I kind of expecting Shouichi somehow escape to make things quite threatening for the group ... nope not happened.
