I think people feel upset and frustrated because they see their beloved character is bullied.😫 They want their hero to be cool and fight with full control of his ability. I feel that too and I also want he fight like the can see through the enemy. 😵
But if I look back to all the matches he went through, I think Isagi still not get to that level yet. His ability is great but his physically, his mentality is still not ready. We can't expect an average player become the top of the player just after about one month and 10 matches, that will be too fast. He still too naive and lack of experience. There so much thing he need to learn. So we need to be patient and wait for he get ready like watch a baby start to walk, he will fall countless time and get up again and again until he master it. 🤗
Try to look other way, it is fun to see Isagi grow when he try to overcome his weakness 😃. The day he stop growing mean the day this story near its ending 😢.
If you don't like the motif of this story, and think it easy to guess, I think you can try to wait until it end to reread it, or wait until the match over (about 8-10 chapters, 2 months). While you wait you can read other story like BE BLUES , Area no Kishi, Giant Killing, Ao Ashi, etc. So you will not get bore. 😉
