Skills from ALICEMAN coins
Instead of damage and defence and other stats, levelling gives you 4 rewards: On its own, the coin can be used as a consumable to do 10 damage, which is terrible because it's you'll lose it and access to your skill!
 * Increase in HP
 * Increase in luck
 * Increase in inventory space
 * At levels 13, 16, 19, 22, 25 and 28, Willis will give you an "ALICEMAN copper coin"

Bring ALICEMAN coin to the blue card location "Monument to the sage (聖人の碑)" (note that 'sage' just happens to be a pun for 'alien' in Japanese) in Leazas field. You will then be able to talk to the wild ALICEMAN that appears and select from a list of skills.

There are 6 skills to choose from.

It's recommended to get the Hyper metabolism and Fighting maniac 1st and 2nd, but don't fuss too much, as you'll eventually get all of them.
