Dead End Tide

[Gripping you with force] these are my ocs

The world is peppered with 'dragons', the Shen - large clam creatures who generate protective illusionary fields, and attack each other within those fields. These attacks consist of illusory shadows that strip away the personality and spirit of anyone unlucky enough to be caught inside.

Minato, a teen with ostensibly no personality with no personality, just gets really, really sick. To make matters worse, the shadows seem to be able to tell there's something wrong with him, and are stalking him wherever he goes. 

Koharu, a girl dealing with the loss of all her limbs, befriends an enormous clam dragon underneath her school, and using her bond with it, she gains control over illusions themselves, allowing her to attack the shadows plaguing her friend.

[Minato and Koharu are 2 unrelated narratives, just set in the same universe.]
