Fujimaru Ritsuka: "Hehe... after all, they're all the kind of guys I can solve with my fists."
Haibara Ai: "You're human, right... Ritsuka?"
Fujimaru Ritsuka: "Yeah! What's wrong?"
Nangong Natsuki: "Are you a witch or a mage?"
Fujimaru Ritsuka: "In our world, I should be called a magus! And honestly, I mostly use reinforcement magecraft and stuff. Runes, High-Speed Divine Words, substitution techniques—I learned a little of everything. What I learned was pretty scattered. Maybe because there were too many Servants in Chaldea, there wasn't any proper teaching system..."
Ritsuka's words made Chu Chen's mouth twitch. She had a point.
Scathach was skilled in runes. What could Mama Emiya teach besides reinforcement and projection? Apparently nothing else. Neither Medea seemed like the type to teach people. Fuuma Kotarou and the others had probably taught her some ninjutsu, with substitution techniques being a typical example. As for the remaining Casters... better not mention them. Every Heroic Spirit had their own specialty, which created major problems when it came to teaching.
Back in 2.1, Kadoc had even mocked her for not knowing clairvoyance magecraft. That showed how these Heroic Spirits had focused too much on training Ritsuka in what they themselves knew, without understanding that they should teach her some fundamentals.
Only in hand-to-hand combat did those people know to make Ritsuka properly train her physical strength.
Ilyasviel: "That's why I really want to complain! Sister Ritsuka, you're a mage, so why are you fighting in melee?!"
Fujimaru Ritsuka: "Huh? Doesn't every mage have a heart that longs for close combat? Isn't that common sense?"
Illyasviel von Einzbern: "..."
Takamachi Nanoha: "..."
Loki: "..."
They really wanted to ask whose common sense that was!
Fujimaru Ritsuka: "Besides, the latest template I got seems to be a composite of King Solomon's 72 Pillars
