Hear, hear.

I had posted pertinent info on the 13th livestream thread back on the 26th (and updated it 2 days later as soon as the devs announced that they'll bring down the cost of it).

Each LB dragon will raise the max level of a fully-leveled rainbow (native or rarity-promoted) by +5, up to +20. For every 5 levels, the unit gains 1,100 stat points (broken down into +750 HP, +250 ATK, and +100 DEF). Four LB dragons are needed to max one unit from level 80 to 100, at the cost of 400 100 rainbow medals, sooo......

1 "Centy" is possibly a reference to the Latin word "centum," which represents the number "100" (being the new max level cap)
Also, Naae is ナーエ; Centy is センティ. They're 2 distinct entities and, thus, have different names.
