Farmville

"I can't believe you locked yourself here… Right under the hill." Kotone says she, Red and Fumio step inside Red's cave.

Fumio meanwhile, accepts it as simply one of Red's oddities.

"But boss. This cave does not seem natural." He observes.

"It's not. It's a product of my own strength training." Red explains to the two.

"Strength training?" "How?" Kotone and Fumio ask respectively.

"Without using any tools, and using just my limbs, I carved this place out. Took me a month actually." Red explains.

The two students are shocked. They cannot even imagine reproducing such feat.

"S-so… that's why you gave your room to Kotone without hesitation." Fumio gets over his surprise.

"Yes." Red confirms as he leads his students to the furthermost wall of the cave.

Kotone and Fumio thought they already had their dose of surprise and shock of the day, but their jaws drop as a huge ring of yellow light appear in front of them.
