Peter Grill to Kenja no Jikan - Episode 10 - Lisa Formally Sits

The way Lisa sits as she talks to another ogre definitely proves she is an ogre princess of their native ogre land, Ogrestan.

The nice ogre man who cheered Peter up last episode gave him news that Lisa and Mimi are princesses of the royal family. Peter confronted Lisa about this information, she confirmed it, and doubled down that she and her sister had to find stronger sources of baby batter to strengthen their native land. Spartokos, who loves Lisa, didn't want to hear that, and challenged Peter to a duel for Lisa's womb. Peter has a hard choice of throwing his fight to make the ogre sisters leave him alone. Things obviously won't work out for Peter the way he hopes.

Geh.

Lisa didn't even care that Peter found out she was a princess because it bolstered her claim that she needed his heir to make the ogre land stronger. She doesn't mind having a conversation naked, leading to NSFW situations.

Lisa admitted that she was a princess looking for strong men because she found the ogres in her land weak and still takes every opportunity to take the jack juice of the best warrior in the world.

Lisa's lack of modesty addressing Spartokos as he barged in on her intimate time with Peter is the best proof that she's royalty and how she thinks of all the ogres from her land as bugs, which is why she came to Peter's warrior guild in the first place. Does a naked lady care when a fly or a cat is nearby looking at her? Nah. That hurt Spartakos's pride, but not as bad as Peter fighting him naked with a banana against his huge axe.
