Totally forgot that I like the thanaka idea. Island sunscreen!
Reviving this thread because I have questions about why Kid was staying with Lucca if Magil knew who she was in the first place.
This is from the "Shea's Light" storyline, but seems like some of it could easilly be used for Lucca's orphanage.
While Kid is lost in thought, Magil takes me aside and explains the rest to
me, alone...
"Kid, still a child at the time, was raised by the holy sisters in their
temple.
However, one day, one of the sisters was summoned to Lynx's mansion. Kid
waited day after day, but the sister did not return.
After some time had passed, Kid secretly sneaked out of the temple,
determined to find out what had happened.
She made it almost all the way to Viper Manor, alone and unprepared. She was
still just a child, after all.
But then, she heard an explosion, back in the direction of her hometown. She
looked back and saw fires everywhere, engulfing the only home she ever knew.
Someone had set fire to her entire village, including the temple.
Forgetting the mansion for the time being, she ran back to town, but Kid was
the only survivor.
Back then, I was a regular visitor of the temple. One day, I came to where
the town had been, and came across this sight. All the village had burnt to
the ground, and there appeared to be no survivors. But, following my
intuition, I searched and searched.
And there, among all the cinders and bodies, crouched a tiny, trembling
little girl.
After I took Kid under my wing, it was an entire year before she spoke
again. Ever since then, I haven't seen her cry a single time..."
But in this scenario Magil didn't have any connection to Kid beyond visiting the magic temple every now and again. So why would he entrust Lucca with her upbringing and not be around when tragedy struck?
I ended up filling in holes with what I knew from Chrono Cross, mostly Kid's subconscious time-traveling power when she's in real danger. Since Kid would only be able to save herself, not Lucca or any of her friends in such a terrible situation, it could have made a temporal distortion around the entire orphanage that Magil would have been unable to break through.
As for why Magil wasn't completely in charge of Kid, he could have been too late in discovering her identity and at that time she and Lucca were more sisters than he was her brother. I can easilly imagine that scenario, "No way you're getting Kid, she's my baby now, go screw". And well, Magus is the guy who sucks plus he's got depression, maybe he realized he wouldn't be much help to a little girl and just poked in every now and again. I like it that way cause it's more Piccolo angst than "WAH I'M ERASING MY MEMORIES" JRPG angst.
