Samurai X/Rurouni Kenshin, I was trying to make it as similar as the anime plus making it fancy so she sounds like she's bullshiting (based on the new ability she obtained). A bit TMI, I know it's supposed to be Battosai instead of Battosei but since the one in korean used the wrongly translated one, I made a slight mistake in it. The korean mistake was supposed to make it sounds like the swordsman is an old man. In which I decided to go with "sei" just because of "Sensei"
