When Shinji was fighting some of the delinquent students from the bad school but one of the classes 4-B and 5-A are watching Shinji fight them but at the same time they are scared of him because he shows his true form of vampire to them.
Delinquent: are you not human anymore?
Shinji: yup I'm not but Shiru kill them and you can eat his heart if you like
Shiru: yes niisan
He starts to run with his vampire speed and they start to run off but Shiru goes and punch his heart out from the body and they fell and bleed out but Shiru just eat the human heart while he has done that Shinji just seats on the floor and look at Shiru kill the human one by one.
Shinji: Are you done yet?
Shiru: almost done
Class 4-B and 5-A make a noise at the behind from Shinji's back but Shiru didn't hurt them just attack the delinquent student only.
Shinji: what did you want? Speak!!
Later they know that Shinji can hear them and we went out and walk toward him and talk to Shinji.
