Just wait Makino.when Luffy will eat Gomu Gomu No Mi you will feel power of the sun.
spoiler for those who dont know yet.Gomu Gomu DF. real name is a Hito Hito No Mi .and it is OP zoan DF.
Nah. The beginning (few chapters) not to my taste. Would be better make her care more for him and only attempt something after he grows (like the time he sets sailing) Right now it looks too unrealistic and that nothing will or should really happen.
