hm?

Yuusha no Shou is the second part of season 2 adapting the 'Hero Chapter'
Dai-Makina is the sequel season 3 adapting the 'Greak Makina Chapter'

(although I haven't seen any of the series so I don't have personal experience, just reading articles)

ik the first part of season 2 first released as 3 short movies before being split later for TV broadcast, which we have as separate entries if that's the cause of confusion?
