A Tsundere can either be sweet before knocking your lights out when you annoy her or be abrasive before showing her hidden softness. Other uncommon types of personality can also show themselves, such as Yandere or Yangire. A more obscure type of personality type that will show up occasionally is the Tsunshun, who uses her abrasive nature to hide her depression. The Tsunshun is the Tsundere equivalent of a pufferfish - she desires to make herself seem spiky and intimidating so that she can protect herself from anything that would antagonize her negative feelings.
