Alright, after reading the Tales Of Symphonia Manga I found out why Lloyd fights with two swords. What happens when he finds out Likana fights with the Santoryu style, a style where the swordsman, or swordswoman, uses three swords (A sword in each hand and the other with the hilt in his/her mouth). If you have ever seen One Piece, Roronoa Zolo uses this same sword style. Anywho, I have come up with this one shot for when Lloyd finds out about the Santoryu style and how Likana finds out why Lloyd uses two swords. (In Travles of Lost Symphonia)

Likana: -Walks up to Lloyd after battle- Lloyd?
Lloyd: Hm?
Likana: Why do you use two swords?
Lloyd: Well, think. With one sword you strong, right? So with two swords your stronger. I thought about it at school when Proffesor was explaining how if you add an apple you'll have more to eat.
Likana: Eh...That's it?
Lloyd: Yeah.
Likana: Then why didn't you just use three swords? Three times the strength?
Lloyd: Umm, because I don't have three hands...?
Likana: For the Santoryu style you also use your mouth to wield a sword.
Lloyd: Really? Wouldn't that be kinda hard to do?
Likana: Yeah, kinda. It was hard to learn to hold the sword properly in your mouth and be able to carry the weight, too. Not just that but to endure when ever another weapon hits the sword.
Lloyd: Whoa, you mean you use the sword style?
Likana: Yeah...?
Lloyd: Someone as short as you?!
Likana: ...

Smack, smack

Lloyd & Likana: Oww!
Lloyd: That hurt...
Likana: What was that for?!
Raine: You two were not paying attention durring the lesson.
Likana: Eh...
Lloyd: A lesson was going on...?
Raine: Yes, indeed there was.
Lloyd & Likana: Oh...
