Hello Yann,
   It's from the movie "Dagger of Kamui," when 
Kamui meets his mother for first time, touching
scene. Very nice cel :) It's a great movie if you
ever get to watch it! BTW: it just so happens
I've been looking for a cel from that movie for
sometime now, so you are very lucky!

Many Thanks,
       Garrett (who's back online now ^^;)
