"there's something wrong here" mercenary. "Why are you floating?" Hiro. Story/Character: Spectral Force hints at large world building of a generic fantasy multi racial war. Watch Nanatsu no Taizai for proper art & story, or Shingeki no Bahamut for epic multi racial battles. But this story isn't as terrible as the synopsis. Here demons aren't typical villains. Demon lord Janus wanted to sacrifice himself by sealing some op excalibur (called "this" by the purple hero) with his body. By removing the op sword he hoped the world becomes peaceful. Hiro is the half daughter who hates humans but somehow has human mercenaries serving her. She's left with herfather's mess. Somehow both demons & humans like to attack her.
Shirou/Harry Potter, a tiny mercenary becomes important to the plot. Everyone has natural or funny dubs, but his is the most hilarious. [spoiler] He later becomes a manslave for a noble cause.
Besides the dry war conflicts. Dialogue among mercenaries, Hiro & other races can be funny. And the strained family relations is somewhat interesting among Hiro, her oneesan, Janus, brother who was banished by Janus, which includes power struggle for the demon clan heir after Janus.

Art: ok. There's a few short combat shots with smooth animation.
Sound: ED & osts are fine, maybe the best part of this (dub the 2nd best). There's even some epic pipe organ.

You can watch Spectral Force Chronicle Divergence for more about the world with better art, but less animation. It seems a remake with similar scenes, but more boring plot cards, dry with no osts & no English subs now. If you'd like something blander, then Chronicle Divergence is the answer.
