Author is mc gonna get a summon or not. I prefer eagle or hawk. If he does go learning sage mode in future his wind maybe enhanced because of them. Tho most of the summons somehow reflect the users maybe Fujin will get something reflecting his shamelessness. đ¤ Also try adding flying to his arsenal soon. I am waiting for wind armour
a little time skip after the next mission ends will be great and now that the mc has knowledge and enough resources(after he becomes an official jonin or at least special jonin he can access virtually all jutsus in the village that are not forbidden ) he can train easily and he can focus on summonings or maybe Chakra body enhancement or sage mode or medical ninjutsu there's a lot of methods he can use to reach the power level of kage by normal means (without needing sharingan or any kekkei genkai ) he first needs to perfect all Chakra transformations( the 5 elements) starting with wind his natural affinity and he has a large Chakra pool that will grow more in the future so he can support the use of strong ninjutsu(S rank ninjutsu or multiple A rank).
