I actually got a Lina plushie last week for my birthday XD

Engagement

1. After so many years of travelling together, Gourry decided that he should marry Lina, but he was too intimidated by her to ask.

2. He kept imagining Lina would go into a mad frenzy and Fireball him to death.

3. Fearing castigation from Lina, Gourry consulted Amelia for help.

4. "We both know that Lina is a belligerent woman," said Amelia. "If you don't want to get beat up, you'll have to present yourself just right. I'll help you. True love will prevail!"

5. Gourry and Amelia knew that Lina had much disdain for public displays of affection and romantic things in general.

6. "You're going to have to find the right time and place, Gourry," Amelia said. "Get her a ring or something, too, for tangible proof of your engagement!"

7. Gourry took solace in the fact that Amelia was so confident that Lina would accept his proposal.

8. There was a rundown magic shop in the dregs of the city.

9. It was run by a friendly octogenarian. Gourry bought a magic amplification ring from him for Lina.

10. Gourry and Amelia ran into Lina and Zel on their way back to the inn. Lina explained that she was going to fight with the local bandit aspirants to "teach them a thing or two."

11. Gourry and Amelia joined Zel and the pugnacious Lina. The new bandit hideout was hidden in the forest east of the city.

12. Lina barged right into the hideout and faced all the sordid bandits. She threatened them with a Fireball and demanded all their treasure.

13. The young bandits scoffed at Lina's threat.

14. "They shouldn't be so brash," Zel remarked. "They have no idea they're dealing with Lina Inverse the Bandit-Killer."

15. Lina heard Zel, and her language suddenly turned scurrilous. She slapped Zel with her slipper, then threw herself at the bandits.

16. Gourry's swordsmanship belittled that of the bandits.

17. Many of them were left with nasty lacerations after facing him, while he was left unharmed.

18. A big bandit fell for Gourry's feint, which allowed Lina time to use a quick spell. While they fought together, Gourry asked, "Hey, Lina? Wanna get married?"

19. Lina accepted with alacrity, much to Gourry's surprise and relief. He could give her the magic ring later.

20. Amelia overheard their exchange and punched a bandit with joy. She couldn't wait to promulgate the news!

I don't think Lina would want Amelia to tell everyone in the whole freaking world, which is what I keep imagining her doing o_o
But like Lina x Gourry ftw.
