Lambda is indeed a sweetheart. I love her but not as much as Tsubaki. Tsubaki is no. 1 in my heart.
You shouldn't see Litchi, as a "goddess" or a "lover" or "good" or "bad".
She's just Litchi. Accept/acknowledge that she isn't perfect and still like her. Despite what she's doing she still has good points and what she's doing is understandable in a way from her point of view.
... I seriously think that's the only reason why people don't hound me for liking Tsubaki so much.
EDIT: I just saw the Litchi sprite you put up SD and even though I've seen it before I lol'd again.
