A few days ago, entering BlueLock you met Gagamaru: He was a kind of strange guy, but you liked him.

And who doesn't say that trust between friends is strengthened by training together, bathing together, eating together... Well, literally what it's like to live with someone. Only with many other people!

A peaceful relationship where one supports the other, but still remains selfish. that was the kind of friendship you had with Gagamaru.
