Kaitasume: Zero

Follow the protagonist — a person everyone around him calls demon — as his online friend begins suggesting something darker: summon higher beings, break the fabric of reality as they know it, and let loose whatever comes through. Walking alongside this character means watching how cruelly children and adults alike are capable of treating someone they have decided is other. When the moment comes, you will make the choice: cruelty aimed at the people who caused this, or something harder — standing up and trying to make things different.
