魔法少女之絆

魔女，原先也是人類，是來自舊世界，也就是前一個毀滅的世界中，游離於世界的生命構造體，但是靈魂遭受到了污染，或是遭到了衝擊而破碎。以失去自我為代價，獲得了&-_¢*？的眷顧，成為了魔法能量極高，目的讓人無法理解的生命構造體。
亞人，能夠適應這個世界，並且能夠存活下來的靈魂們，他們是被宛如鎖鏈禁錮的種族，獲得了微量的魔法，以及較為敏捷的身軀，但是身體也混入了獸性。但是在亞人千百年來的研究中，亞人們也學會使用自身的微量魔法來讓獸的本性隱匿起來的魔法，也是目前世界上最為和平的種族。
魔法構造體（魔物），很多是無法構成意識，或是由破碎的靈魂所構成的，很多時候他們只是破碎靈魂的複合體，但是他們也渴望著獲取完整的靈魂，所以會自發的攻擊靈魂完整的生物。
在這個世界上，不論是魔法構造體，還是生命構造體都至少擁有著微量的魔法，魔法的粒子也是飄散於世界中。
舊世界，在傳說的神話中，是前一個文明水平相當高的世界，但是因為不明原因毀滅了，在舊世界人們的靈魂們，似乎都會因為某些干預（？？？），而來到這個世界。

Magical Girl's Bond

Witches, originally human, hail from the Old World, the world before the previous destruction, existing as disembodied life constructs roaming the world. However, their souls have been contaminated or shattered due to trauma. They gain the favor of &-_¢*?, becoming beings of immensely high magical energy, with motives incomprehensible to humans.

Sub-humans, souls capable of adapting to this world and surviving, are a race akin to prisoners bound by chains, granted minimal magic and agile bodies, but also imbued with animalistic traits. Over centuries of study, they've learned to use their minimal magic to conceal their beastly nature, making them one of the most peaceful races in the current world.

Magic Constructs (Monsters) often lack consciousness or are composed of shattered souls, sometimes just conglomerates of fragmented souls. Yet, they yearn for complete souls, hence spontaneously attacking beings with intact souls.

In this world, whether Magic Constructs or Life Constructs, both possess at least a trace of magic, with magical particles scattered throughout the world.

The Old World, in mythical legends, was a world of significantly high civilization. However, it was destroyed for reasons unknown. Souls from the Old World seem to arrive in this world due to some form of intervention (???).
