I just read the description and honestly it looks awsesome but the only thing that sucls is that the MC is and stays a F-rank even though he has a SSS-rank skill that allows him to fuse things together but honestly it would be cool if the MC can either work his way up from F-rank or finds something that allows him to raise his rank or taks some kind of fruit or something that is supposed to strengthen ur rank or whatever but have him find a lot of them and I mean A LOT and have him eat them all at one time have him raise his rank that way but have it almost kill him and give hi incredible pain or something.... and at the same time have it come from a tree or something that can be taken an replanted somewhere where he can keep it safe and then have him get other special things that will help him and the things he fuses together and have the special things he gets and brings back to the place where he can keep them safe have them grow and/or become more powerful when they get used so how ever he grows them or raises them its special and then they become special... hope this helps with ideas!!!
