Story ★★★★★
The story involves reenact human history, yes the same stuff as on our textbook
therefore we know how it happens and ends, but the ways they are done by the Anime is very imaginative and surprising
For example, the fight scenes of main battle in the second season - reenactment of the Invincible Fleet Naval War: Musashi as mercenary of England VS Blessing fleet of Tres Espana
P.S pretty funny for Toori (main char) running around naked most of the time (even in International Meeting with national leaders)

General ★★★★★
Again, excellent battle system
Just like the first season, fast moving plot
Although again, the story setting is very hard to understand unless you read the novel or do some research
BUT, very very informative

Design ★★★★★
Fabulous weapon designs merge from historical items for instances: Excalibur from England, San Martin from Spain (Tres Espana)
and beautiful yet cool character costumes

CG ★★★★★
Nicely done CG to enhance the battle system

Music ★★★★★
Absolutely awesome BGMs, as of now total 2 OST releases together containing 4 CDs total almost hundred sound tracks
Most, yes I mean most of them are stunning!
Plus I don't really like the OP but the 2 EDs are above average
