For example Episode 18, Eva-Beatrice refuses a repetition request by saying 'I refuse!' Sounds like 'kyohi suru wa'.
In episode 9, Beatrice says 'I refuse.' Sounds like 'kyohi suru'.
In episode 14, Beatrice says more elaborately 'I refuse to repeat it.' Sounds like '復唱 kyohi suru' (Fukushō o kyohi suru).
What exactly are they saying?
Are they actually removing the personal pronoun 'I' (eg watashi or whatever) and so are just saying just 'Refuse' or 'Refuse to repeat' ?
