Admittedly, Riki doesn’t make a strong impression at first and he won’t strike you as an interesting protagonist early on. He’s not returning into a town for the first time in 7 years while lacking memories of that place, he’s not a mysterious traveler, not a gun-wielding scavenger in a world that rejects life, not a delinquent and he’s got no superpowers, either.
He’s an ordinary boy in an ordinary school where he and his friends make the most of their ordinary everyday life. The only irregularities in his concept are dead parents and a sleep disorder.
Yes, his concept, at first glance, doesn’t seem interesting. But that’s ok. Because ordinary means peaceful.
Riki is a protagonist who’s good at whatever he’s currently needed for.
As long as his life is ordinary, he doesn’t need to stand out. He only needs to be able to have the most fun and be happy.
Recruit members for a team? No problem. Riki can approach just about anyone naturally and he’s got zero enemies. He’s nice and always ready to help. He won’t tease people for the fun of it - his comedy routine is retorting, not attacking.
Even when things get serious and someone close to him is in real trouble, Riki will demonstrate incredible dedication and willpower. He will stand his ground and do everything he can in order to support and save his loved ones. Sometimes he’ll fail due to lack of strength, only to come back stronger and face the challenge again.
He’s not strong and capable from the get-go, but his mentality allows him to grow stronger over time.
The same is true for his concept: It’s not unique and interesting at first, but it becomes amazing later on.
And hey, he’s good at talking to girls. That’s an awesome skill. He’s not the handsome senpai type, but he can win over most girls naturally.
