I recognize the first part of each one says "to aru Sheriru" and "to aru Brera." Like "for Sheryl" and "for Brera?" But I can't really figure out the last bit. I'm still a bit rusty on translating kanji (haven't done so for about two years now). Sorry I can't be of more help, magnus.
Edit: or wait... that's "to aro"...
Second edit: the first character in the one with Sheryl is "ai," or "love," as it would be. Underneath the whole bracket, the first three character spell out "Saotome."
