In case anyone's curious as to what the videos are saying (not much, really)...

====================1st Video========================
(first two lines of text in the video)
秘宝を集めてどうするの？
まさか神になる気？
What will you do once you find all the hidden treasures?
Don't tell me you plan on becoming a god?

(last part of the video)
Human: Grow stronger by fighting enemies.
Esper: Learn unique dragon powers.
Meka: Improve stats by adding weapons and armor.
Monster: Grow stronger by eating enemies and changing form.

====================2nd Video========================
これはだれにもわたしてはいかんぞ。
いいな？
Don't give this to anyone.
Got that?

またどっかいっちゃうの？
Are you leaving again?

ああ。
母さんをたのむぞ。
Yeah.
Watch after your mom.

ウン・・・はやくかえってきて・・・
OK...come back right away...

・・・わかった。
元気でいるよ。
...Alright.
I'll be fine.

なんで父さんって、
いっつもまどからでてくんだろう？
Why does dad
always leave through the window?
