I FINALLY GOT TAKUMI!
Here was my reaction as summed up in three pictures:
1) The moment Takumi's summoning cutscene began:
2) Me from the moment after Takumi's summoning cutscene until the stars above Takumi's name appeared:
^Unlike Bonnie in this picture, I was screaming out of joy for a good minute.
3) Me for about a good 5 minutes after the Takumi summoning cutscene played:
Three months. It took me THREE MONTHS to finally get my favorite Fire Emblem character. You don't know how happy I am a finally summoned Takumi!
I don't care if Takumi already has several counters. He is going on my team regardless. In fact, I already started training him up, and he is currently level 31. I grinded up my Lon'qu as well and used him to give Takumi Vantage 3, so now Takumi has the tools necessary to become the destructive unit that he is. I just need to get him to Level 40, then grind up some SP for him, and he will be all set.
Here were the other characters summoned for those that are curious:
I already have a 4-star Sully and Fir, as well as 3-star+ Palla. Wrys? Eh, don't really care for him.
