Due to his inability to properly speak Japanese, he is initially seen mostly nervous, but slowly gains confidence as he learn them. He is also quite naive as he blindly follows Kisaki's instructions, clueless to the fact that he's being turned into her personal errand boy.
- Kisaki Kondou: As she is the only person who he can properly communicate to, Saiki became dependent towards her and blindly follows her instructions as he trains under her.
