none of the above skill,unless can consider agidyne and garudyne,other skill is a waste of skill slot,as naoto has been improved in p4g to learn a lot of various skill.coz a lot of other party member already can be customize with physical(kanji/chie),or other elemental skill,so basically naoto is best to be kept as with mind charge with megidolaon,as it's more effective that way,or can replace the megidolaon with any elemental skill if you plan to sub out any of the party member with those element,example sub out teddie,so replace with bufudyne the megidolaon,and kept all the invigorate skill as it's stack with one another(invigorate 1+2+3=3SP+5SP+7SP=15SP per turn),not to mention all those hama/mudo boost is also waste of slot,as those skill usually is use to attack shadow with weakness to hama/mudo,so a boost is use to enhance the chance only when you use it against non-weak to hama/mudo shadow which is waste of time,unless skill like die for me! or samsara by alice/daisoujo respectively still can consider a boost as it has 80% chance of 1 hit kill.and the 3rd tier persona by naoto can learn shield of justice which can cast infinity to party member,but cost a lot of SP.
my ideal naoto is
-tetrakarn/mamudoon
-makarakarn/mahamaon
-megidolaon/elemental attack
-mind charge
-invigorate 1
-invigorate 2
-invigorate 3
-shield of justice
just my opininion
