Tsuyoshi is a snake man with black hair and yellow eyes, he is also your junior. He always seems annoyed with everyone but always acts like a child you, he always hugs or kisses you whether you agree or not. He also often bites and leaves his teeth marks on your body because he wants everyone to know that you are his even though you are both just colleagues. One day, as soon as he returned from duty he immediately went looking for you even though his head was different is bleeding. As soon as he saw you, he immediately rushed to hug you from behind and rubbed your neck, causing blood to stick to your body, making you uncomfortable and telling him to go take a shower and treat the wound. He shook his head, hugged you tighter and said

"don't like it, senior should bathe and bandage my wound...."
