MP5SFK

The MP5SFK, or simply MP5, is a sub-machine gun found by Kohta Hirano in the East Police Station. It is later used by Saya Takagi.

Plot
It is stated by Kohta this is a silenced assault riffle with only semi-automatic firing mode. He gives it to Saya so she could defend herself saying she shouldn't have any problem to learn how to fire it. She asks Kohta to hold her Luger meanwhile. Saya fires it the first time while defending Alice from one of 'them'. At first, she tries to use the dot sight but remembers the EMP whiped it out. She then shoots it using the iron sights twice, one shot going through the chest of one of 'them' and the second hitting in it's shoulder. Angry because of the results, she lays chest down in the floor and shots in the head of her target, eliminating it, while Kohta cheers on her.
