Traveling to the world of Naruto, Tetsu Kanhara mentioned the TFT Hex system.
Looking at the various heaven-defying enhancements on the panel, he set an iron rule for himself: stay tight, don't wander, and live safely until the finale.
However, this system really understands the "optimal solution".
The battlefield is on the verge of death, and the enemy needs to hit you last time. Choose one of the three to activate.
[Brain]: As long as you stay alive, just choose one that will save your life!
[System]: Select to confirm! Hex Enhanced [Binary Airdrop] has been loaded! We are adding "conceptual sharpness" and "structural stability" to your inferior kunai... Congratulations to the host, you have completed the ultimate counterattack against the enemy ninja!
Take root in Konoha, complete the task, and choose one of three rewards.
[Brain]: You have to practice chakra secretly. Battery life is the key.
[System]: Select to confirm! Hex Enhancement [Source Plan: Uplink] has been launched! The passive chakra recovery circuit is established... Congratulations to the host, for obtaining a long-lasting battery life comparable to that of a tailed beast!
Possessing such magical skills, Toru Kanhara tearfully formulated a perfect plan for himself to disguise himself as a "middle-class student".
As a result, on the day of the entrance test, he completely lost his temper in front of the whole school.
When an S-class file about "a seven-year-old orphan who is suspected to have returned to his ancestors and possesses jounin-level throwing skills" was quickly placed in front of the Third Hokage, Kanbara Toru was about to cry.
"Sandaime, please listen to my explanation! I really don't want to show off, I just want to play Genting quietly!"
It's okay, quite novel.
