Asuto is sadly the least relevant main character Hissatsu wise

Like he knows 2 solo moves, 3 group moves (I counted fire ball storm even if it's just shining bird) and is working on last resort

Endou in 26 episodes knew 4 solo moves and 4.5 (tri- Pegasus and the Phoenix same really) group moves

Tenma in the same amount of episodes 3 solo moves (upgrading Mach wind fully) 1 group move 2 avatars and a combined avatar

Asuto should be more important wright? What do you think
