■ Welcome to the future where VilleHaven's technique of replacing parts of the body with machinery "Jagir" is widely available. A city splits into three tiers, coexisting in a dangerous balance. Above the sky where the privileged class lives-the Elgrond (the aerial layer); the inaccessible place where light cannot reach-the Undergrond (the underground layer); and the Midgrond (the intermediate layer) caught in the middle and struggling to survive day after day. ■ Explosive Blue, another ordinary day. A small private detective agency located in a corner of Middlegrond, which takes all kinds of chores, a small change commission, has gradually evolved into an event that shakes the bottom of the city. There is no money and no background, but a happy group that can always stick to the commission to the end ■ Six-attribute restraint, six-attribute restraint that bites the strength and weakness, each step determines the outcome · The protective stone breaks the attack to reverse the situation and returns the clever use of attributes · The strategy achieved by BP, the shared combat resources accumulated by the whole team · Each team combination can create its own battle ■ More than 60 heroes with their own stories · More than 60 unique characters written and depicted with heart · Personal narrative "pocket story" depicting the background of each hero · Share with your team growing partners.
