When Ren looked back at his statistics, he understood what Mizuha meant.
In just a week of training with Taiga, Ren's strength in normal mode had increased from 9 to 10, and his strength in Felis Ignis mode had also increased from 22 to 24.
Besides strength, the improvement in his attributes was also noticeable in agility.
[Agility: 10 (31)] => [Agility: 11 (33)]
This increase occurred because Ren had to dodge Taiga's punches, as even a single hit would result in a barrage of continuous blows.
Lastly, his stamina attribute increased by one point, both in human mode and Felis Ignis mode.
"Sensei, the reason I've improved so quickly is because I'm not yet used to Senior Taiga. Over time, this progress will eventually slow down because he won't be able to push me as he did before. You, Mizuha-sensei, are stronger and have a higher upper limit, so there's still a lot you can teach me," Ren pleaded with Mizuha.
