[@Sho Minazuki] How are support ranks being determined and levelled? Like is it honor system for that?

If there's sufficient interaction, you are allowed to create a support conversation and send it to me for approval. Once approved you gain a rank in the support.

For what counts as sufficient interaction, it depends on the topic of the conversation, and the rank you're trying to go for. For example C rank won't take much effort, just convincing enough interaction. But A and especially S rank will need a fair bit of work.
