Episode 19

Maxing Defense and Hunting for Crystals is the seventh episode of the second season of the BOFURI anime series.

Summary
At the Maple Tree HQ, Sally and Maple sit a table while enjoying some snacks when Frederica barges into their base to challenge Sally to a duel. She intended to finally win against Sally and showcase her new "Cute" companion.

Outside, Sally formally accepts Frederica's duel, and they're transported to an arena setting where Sally quickly defeats Frederica in record timing. Returning to the Maple Tree HQ, Frederica shows her monster companion a little chick monster named Notes.

Just then, Dorazou appears before them and announces the details of the Eighth Event. The event was split into two parts, a Preliminary and a Main Event. The Preliminary Event was individual-themed like the first one, where those who survived it will participate in the Main Event. Once the announcement was over, Frederica tried to challenge Sally to another duel, but couldn't because Payne summoned her, so she left.

After speculating what type of companion Frederica's monster was, Sally and Maple decide to wander the plains of Level 7 and reach there by riding on horseback.

Afterward, Maple and Sally are carried by some Uni-sheep while inside Maple's Wooly fluff to a lake with a spot shining in its center. Syrup fetches it, revealing it to be a white crystal, which Maple learns is one of three keys that unlocks a specific door. Figuring there's a condition to activating the quest related to the crystal, Sally deduces it's related to traveling monsters like the Uni-sheep that carried them there.

Later, after exploring the deep sea area, Sally finds a giant monolith with a map of Level 7 with a mark of where they found the crystal by the lake.

Eventually, they return to the Maple Tree HQ and ask Kanade to look at the map in hopes he'd have some information on clues where to find the remaining two crystals. Recalling some intel he read from the library, Kanade discloses information leading them to two bosses holding the remaining crystal keys.

The first boss was a Red Variant Silverwing located in a forested area, which was overwhelmed by Maple's skills and power. Once it is defeated, the boss drops a green crystal called a "Green Key". Sequentially, Maple and Sally head to the next boss in a dark and cloudy sky area where a Wind Golem was at. The Wind Golem blows Maple out of sight, leaving Sally and Oboro to take it on alone temporarily. However, while firing off a giant laser beam, Maple returns, now dressed in a green and white dress. Thanks to Maple's attack support, Sally defeats the Wind Golem, making it drop the final crystal, the Red Key.

Now in possession of the three keys, Maple and Sally take them to a ruin in a forest that transports them to a tranquil place loaded with tons of docile monsters. Syrup and Oboro then rush to a small pond in the center of the area. It's there that they bathe in the small spring and evolve into new forms.

Back at the Maple Tree HQ, Maple and Sally show off Syrup and Oboro's new forms to their comrades. Maple had hoped to get their comrades to evolve their companions; however, they visited the same areas in the past and didn't find the bosses Sally and Maple faced off against. It's believed Maple and Sally activated the companion quest because of their companions' level and strong bond with them.

Unbeknownst to the group, they were being monitored by the Administrators, who complained about the game bugs that Maple and Sally again exploited. They then change their conversation to the next event and prepare themselves for what's to come.
