1x3 - Tests Are a Huge Annoyance!?
April 17, 1991
The entire Class 5-3 average match score of the last test is far below the rest of the other classes and needs to do a retest. Asuka, Kouji, Maria and Tsutomu are assigned to help Jin with his studies as his test score is zero. Jin tries to run away, but in the end can't escape. The next day, right before the retest, Jaku Beast Testora appears and Class 5-3 needs to sortie. After defeating the Jaku Beast, Class 5-3 does the retest much to the dismay of Jin. A couple of days later the tests are graded and Jin has 80 points.

During an excursion, the boys of class 5-3 gets into a fight with the boys from the local.

The next day, Class 5-3 hears that Onoboori mountain (the place they went yesterday) became treeless and a Jaku Beast is attacking. Still remembering the fight, Jin is reluctant to sortie.
