In the land of Clardona, two races are in constant conflict over the land and its spirits, the humans, and the beast-like Kascuza. Though the war has yet to fully cease, an interrim of peace can be found on the tiny island of Jarazi. Here begins the story of the main duo, Reiha, a human girl with spiritual powers, and Aldo, a Summon Beast she summoned seven years prior. They have lived here for as long as they can remember, about to set out and complete their coming of age ceremony.
- Artificial Stupidity: The partner AI doesn't know how to avoid spikes and poison pools. You must lead them away from those areas.
- Color-Coded Elements: The five elements, Earth, Wind, Fire, Water, and Sky, are yellow, green, red, blue, and purple respectively.
- Difficulty by Region: Non-Japanese versions of the game start Aldo and Reiha with boosted money, skill points, items, and pre-learned high-ranked skills.
- Fantastic Racism: Humans are described to generally look down on the Kascuza. Additionally, Nassau isn't very friendly to most of the humans he meets.
- Guide Dang It!: The game never mentions tells you that characters are invincible while they are casting. Leading many players to wonder why none of their attacks are able to damage bosses that can cast skills.
- Guys Smash, Girls Shoot: For the most part, the guys are melee fighters, while the girls focus on ranged attacks or magic. Lila is an exception though, fighting with a spear and some magic. The protagonists make this clear when selecting the lead, with Aldo being skilled with melee attacks, and Reiha being skilled with magic.
- Hello, [Insert Name Here]: Both protagonists can be renamed, though doing so would remove their name plate in their dialogue bubbles.
- Humans Are Bastards: What with the capturing and exploiting of Summon Creatures and all.
- Like Brother and Sister: Aldo and Reiha, despite him being a Summon Creature summoned by her. However, they were raised as brother and sister for the past seven years. Can be subverted to Not Blood Siblings depending on the ending you get (and how you interpret them).
- Little Bit Beastly: The Kascuza have animal-like tails. Most humans call them demi-beasts, a name Ayn and Nessau are not fond of.
- Relationship Values: Every character besides the main character has a support rank measuring this. At the end of the game, this determines the ending you'll receive.
- Tech Tree: This is how the protagonists learn their skills, accruing skill points to unlock and strengthen them. The skills have a level cap, however, requiring scrolls to power them up beyond the cap.
- The Glomp: Aldo throws himself at Reiha early in the game, after finding out that she's been fine after they were separated.
