Taylor, you can control Roxanne and Emily's movements.
I believe it'd be much better than me having to control four characters. (I'd go insane
)
Anyway, Yoshiro is the oldest, especially if his true age is unknown.
Roxanne is the youngest, for she is just 6 years old. (Wait, rhetorical question - since when are such young characters even allowed to participate in combat in RPGs?
)
Of all my and Taylor's characters, Shane is the oldest, Taylor the second oldest and Emily the third oldest. (I turn 18 on 25 February 2014, and Taylor turns 18 on 1 June 2014, and Emily turns 18 on 13 September 2014, in-RPG.)
