Richard: Alright, Legend. When I charge at them, be ready to make your move.
Rachel: Are you mad? You can't just charge at them like that... haven't you realized, brother? He uses many different swords! You'll be at a significant disadvantage!
Rachel used "Wall" to boost everyone's defenses. Her concern for her brother was written all over her face. She sounded worried as well.
Richard: There is one key detail you have failed to realize, dear sis… he has many swords, but he never uses more than one of them at once! That is something I can work with!
Rachel: Oh! I see... You are pretty sure about yourself, aren't you? If that's the case, then I won't doubt you!
Richard: Do not worry, sister. I too have a plan! No time to waste! Be prepared!
